// trying to do this:
var fn = new Function("foo", "bar", "baz", "return foo + bar + baz;");

// with arbitrary number of args:
var args = ["foo", "bar", "baz"];
var src = "return foo + bar + baz;"

// with a non-ctor fn i'd do:
var allArgs = args.slice(0);
allArgs.push(src);
Function.apply(null, allArgs);

// but can something similar be done with a constructor?
