Extending 15.28 to include toString() on an enum constant

Remi is correct - 303 has the potential to special case toString()
method calls on enums. One thing that 303 lacks, at least at the moment,
is the ability to redefine what goes into places where a constant
expression is expected (case labels, annotations, ...). That is, the
additional constant propagation occurs *after* type-checking, and it's
mostly there to support code generation. What you ask would have an
impact on the language frontend (and would therefore require some spec
text for it) - I'm unsure as to whether this falls within the scope of 303.
