Joel,
wouldn't this transformation work?
{{{
foo_Names = ["FOO_0", "FOO_1", "FOO_2"];
fooFuncs = { getMessage: [getMessage1, getMessage1, getMessage2] };
}}}
Enum's then become integer ordinals. `FooEnumType.name()` would return
`foo_Names[ordinal()]`
`FooEnumType.func()` would invoke
`fooFuncs[obfuscatedFuncName][ordinal](args)`.
The problem is, by the time you reach the JS AST, you've lost any idea that
these are enums. So it would have to be done at the JDT->Java AST stage I
think.
This is a special case of object inlining where you know that a given type
can only be instantiated with N different permutations, all field values
statically known at compile time. In which case, you can rip all of the
object's fields out to global singleton and replace them with a pointer
(integer or other reference)
