Global option to ignore conditions in immediately executing function arguments

[JeroMiya]

OK, this issue was rejected:

Here's another attempt. Maybe a more pragmatic solution? How about a global or scoped option to automatically ignore branches in the arguments of an immediately executing function declaration. This is most commonly used in the internal module pattern in JavaScript, and by various code generation tools.

Example:

/* istanbul ignore iefa */
var app;
(function(app) {
  (function(common) {
    common.Foo = (function Foo() { this.foo = 'foo'; } return Foo; }());
  })(app.common || (app.common = {})); // these branches ignored
})(app || app = {})); // these branches ignored
