Attempt to wrap the `console.log()` method of the browser and successfully bind to the client object calling `logger.debug()` and not the logger itself.

// I've created a simple logger (wraps console.* methods) that provides output similar to say Log4J or other robust 
// loggers out there for the enterprise, but a huge missing piece (for me) is that you can no longer see the file 
// reference and line number from the client object using the logger. When you use console.log() OOTB it'll spit out 
// a clickable link to the file and line number that executed the console.log making it easy to debug; when you wrap 
// console.log it simply spits out the logger file reference and the line number the console.log was executed, so 
// all logging shows up as from the logger wrapper (which is technically correct)...bottom line, you lose the context 
// from which you actually made the logging call and I'd like to get that back.

// Aside from blackboxing, is there another way to wrap console.log() such that it binds to the client callee
// and ultimately shows the correct file reference and line number of the callee (and not the log wrapper)?
// @JohnYanarella pointed me to the blackboxing solution for Chrome Dev Tools via Paul Irish 
// http://bl.ocks.org/paulirish/c307a5a585ddbcc17242, but I'm looking for a code-only solution...possible?

// `console.log.bind` is used as an attempt to force the client calling `logger.debug()` to save
// the correct line numbers and file so it shows up correctly in Chrome Dev Tools' console and not as 
// those of the logger itself.
var logFactory =
{
	// Correctly displays the client object filename and line number that called debug(),
	// but we can't manipulate the input.
	getLoggerA: function () {
		return {
			// I want to intercept the args being passed to debug() from the
			// client object calling so I can further manipulate the actual log
			// and not hardcode to say "MAGIC"...so in the example below, how do we 
			// capture the incoming "BMR" and change it to "BMR, TJM, AG"?
			debug: console.log.bind(console, 'MAGIC')
		};
	},

	// DOES NOT correctly display the client object filename and line number that called debug()
	// and shows the logger itself, but does allow us to capture the input...
	getLoggerB: function () {
		return {
			debug: (function () {
				var logFn = console.log.bind(console);
				return function (msg) {
					logFn("PREFIX ", msg);
				};
			})()
		};
	},

	// DOES NOT correctly display the client object filename and line number that called debug()
	// and shows the logger itself, but does allow us to capture the input...
	getLoggerC: function (context) {
		var Logger = function(context)
		{
			this.context = context || "DEFAULT CONTEXT";
			this.logFn = console.log.bind(console);

			this.debug = function(msg) {
				this.logFn(this.context, msg);
			}
		};

		return new Logger(context);
	}
};

logFactory.getLoggerA().debug("BMR"); // output >> "MAGIC BMR" with correct line numbers and file ref
logFactory.getLoggerB().debug("BMR"); // output >> "PREFIX  BMR" with incorrect line numbers and file ref
logFactory.getLoggerC().debug("BMR"); // output >> "DEFAULT CONTEXT BMR" with incorrect line numbers and file ref

@ThomasBurleson Some context...I've created a simple logger (wraps console.* methods) that provides output similar to say Log4J or other robust loggers out there for the enterprise, but a huge missing piece (for me) is that you can no longer see the file reference and line number from the client object using the logger. When you use console.log() OOTB it'll spit out a clickable link to the file and line number that executed the console.log making it easy to debug; when you wrap console.log it simply spits out the logger file reference and the line number the console.log was executed, so all logging shows up as from the logger wrapper (which is technically correct)...bottom line, you lose the context from which you actually made the logging call and I'd like to get that back.

If you want to see exactly what I'm talking about you'll need to drop the logger code into one file, let's call it Logger.js, and then create a second file called FooBar.js that calls logFactory.getLoggerA().debug("BMR"); and run it in the console...you'll see that the file ref and line number are for Logger.js and not FooBar.js.

@Codecatalyst I see your tweet with the following updated "Issue 1859293002: [DevTools] Move Console to v8_inspector (Closed)", but haven'r had a chance to see if this fixes the issue: https://codereview.chromium.org/1859293002

And sorry for the delayed response @ThomasBurleson as I didn't realize gists no longer notify you when someone comments: isaacs/github#21
