Why won't it ever be cross-platform? Would the effort just be too gargantuan?

It's too directly tied to the Windows API. The vast majority of non-language code would have to be rewritten to run correctly, unless they emulate the Windows API instead.

There's been many attempts over the past 5 years and IronAHK got the closest, but yeah both languages rely 100% on Windows specific APIs. I hope later on to write an AHK to JavaScript compiler/interpreter. This would make the language more portable.
