The optimization may also be done outside a compiler, dissassembling,
optimizing, assembling.
It is rather hard stuff to programm, though. I am just in phase of reading
about theory again -- got this years ago at university but do not remember
all details.

All I can see now is that everything is a variant, So we do not have byte
code, but variant code :-)

I have not looked too much into AVM2.

This is indeed a problem, also in C++, you can not link to a library which
was compiled with a different compiler or the same compiler with different
options or the same compiler with same options but different version
number... Each compiler has differnt kinds of name mangeling and you can
modify them by the compiler options...
In C++ this is resolved by declaring functions as standard C and importing
them with extern "C" { ... }
At this point, we may extend the language
maybe
overload function foo(id:string)
or
external fooFromOtherSWF;
Maybe compiler may find out itself which functions are overloaded and need
name mangeling, in this case we would need two passes for compiling. Of
course you can not call a name mangled function in a different swf compiled
with a different compiler (like in C++ also does not work).
