It will come down to what you get for that optimization that breaks the
mapping from byte code to source.  Even if it is 10% for 1% of the cases,
then I would say it isn't worth it, or at least, a non-default option, and
the framework needs to work well for the other 99% of the cases, and I am
saying I would drop 100% backward compatibility rather than break that
mapping.

The MSVC compiler can do inlining and tail call optimizations that greatly
speed up the kind of things I think the 99% is going to need without making
it totally impossible to map backward from bytecode to source.

So yeah, I'm all for some byte-code optimizations and some fudging of the
language rules (so you really can inline a constant), but I am still hoping
a class definition will be same everywhere so newbies have fewer things to
learn to be successful with Flex.
