Not true. The ActionScript compiler doesn't know that OBJTYPE_BOX is a
compile-time constant (i.e., it's value might change during execution).
Therefore, the value of OBJTYPE_BOX needs to be looked up, and it's not just
as fast.
Enums are not supported in AS2, but it's a future reserved word in
ECMAScript 4, so maybe with Flash 8 we'll see them. Whenever I do
enumerations, I follow this:

If you want "real" enumerations, write your code with them, and then do a
find/replace before you publish your .swf.
