Yes, that makes sense I guess. I see you're using the preprocessor
a lot for cases where the API changed between AVM1 and AVM2, but
use mostly the same code otherwise.

I could imagine that Haxe is a bit behind when it comes to employing
the whole spectrum of AS3.0 opcodes/features (like namespace
visibility, prototypes of (slotted) inner functions, finally-style
lookupswitch etc.), but that's stuff that doesn't have an AS2
equivalent, anyway.

Speaking of which, as3compile has its own testsuite (only for 
syntax/bytecode, not for API), that generates all kinds of obscure
(but working!) bytecode combinations. I wonder whether you can use 
that for testing Gnash's AVM2 implementation, too:

Well you can use the built-in typeof(), but that's about it. as3compile,
unlike Haxe, doesn't have it's own API. 
Maybe whatever Haxe does for "Type.typeof" can be ported to vanilla
ActionScript.
