Trying to mimic "method missing" in Node.js. Purpose: Allow snake case always. Problem: Don't seem to be possible to forward argument attributes?

method_missing_example.js

var inspect = require('eyes').inspector({
      styles: {
        all:     'cyan',
        label:   'underline',
        other:   'inverted',
        key:     'bold',
        special: 'grey',
        string:  'green',
        number:  'magenta',
        bool:    'blue',
        regexp:  'green'
      }});

function missinMethod() {
  console.log("missinMethod()")
}

// Mimic "method_missing" in Ruby.
process.on('uncaughtException', function(err) {
  inspect(arguments);

  if (err.arguments.length) {
    var method_name = err.arguments[0],
        method_name_camel_case = method_name.replace(/(_[a-z0-9])/mg, function(a) { return a.replace('_', '').toUpperCase(); })

    if (typeof eval(method_name_camel_case) === 'function') {
      console.log("Proxy method: %s => %s", method_name, method_name_camel_case);
      eval(method_name_camel_case + '()');

    } else {
      console.log("No such method: %s => %s", method_name, method_name_camel_case)
      // skip
    }
  }
});

missin_method("foo", "bar");
