John,
I am not a big fan of the exotic identifier proposal mostly because
i doesn't understand the need and because using '#' creates conflicts
with several closure proposal (BGGA and CICE) and my modest
property proposal.

Correct me if i'm wrong, you need exotic identifiers if you are
a language developer that want to implement a part of the
langage runtime in Java. But if you are a language developer,
you control the compiler of that language so you can lookup
for extra meta-data when you want to call a method, a field
or a class written in Java.
By example, these metadata can be implemented using annotations
with no problem.

cheers,
Rémi
