[haXe] Why haxe do not support that?

[Nicolas Cannasse]

> 1) no built-in error class

Any value can be an exception is haXe. There is no need to define a
class to throw a custom error.

You can use Reflect.callMethod instead of Function.apply
"arguments" and "callee" are two features that are not supported,
because they need native support which is expensive in terms of
performances.

> 3) do not support variable length parameter

See up.

> 4) lack some inspect function, such as get the object which a method
> belongs to, get the class which an object belongs to

Everything is in the "Type" API : http://haxe.org/api/Type
