Static Extension (Language Features) - Haxe - The Cross-platform Toolkit

Haxe is an open source toolkit based on a modern, high level, strictly typed programming language.

What happens if the variable I'm using the extension on is null?

final x: Dynamic = null;
x.anExtensionMethod();

[Gama11]

That depends on how the extension method's implementation handles null.

Why using Main.IntExtender instead of using IntExtender? IntExtender itself is not inside of the Main class.

[kLabz]

using x.Y.Z means using package x, module Y, type Z, and not class Y. IntExtender is inside module Main.

IntExtender itself is not inside of the Main class.

This wouldn't make any sense anyway since Haxe doesn't allow defining types inside classes.

Oh, that makes sense. And, I guess, just using IntExtender doesn't compile, even if called from the same module...

Interesting, the manual doesn't seem to mention that anywhere, so I haven't even checked. But that's good - simpler language = less headache.

Thanks for clarifying!
