[antlr-interest] Filtering Java expressions

[Junkman]

Hi Bill,

Just throwing up a suggestion here (haven't thought it through).  Lex
the input, ignore comments and parse the rest into statements (ending
with ';') and blocks (ending with  {} block) containing statements, and
then try to parse each statement as variable declarations.  Would you
need to determine the context of the variable (local, class, etc.)?

If you expect to target other Java phrases and/or their context, you
might be better off writing the full grammar first.

Hope others will chime in with better suggestions.
