Garrett, I gave a specific use case for why I'd like to be able to
specify
the name on an anonymous function: wrapping an existing function
with pre-
or post-call behaviour.
I think I get it.
It seems like just giving the function a name (not *anonymous*) would
fulfill that need.
Example:-
<script>
var getX = (function(){
var x = 10;
function getX() {
return x;
}
return getX;
})();
document.write(getX.name + ": " + getX());
</script>
It is sometimes unfortunate that Function's Identifier can not be set
from a string value, without resorting to `eval`. Descriptive
Identifier's make debugging easier. A simple example of some kind of
constructor creation facility shows what I mean:
var Class = {
create: function(name) {
var fn = eval('(function ' + name + '(){})');
// set up inheritance, etc.
return fn;
}
}
Class.create('Person'); // Person()
I think it could be beneficial if `Function.create` would allow for
such control.
