I'd rather have an option globally settable, non-intrusive,
forward-compatible; with a clear note, "this will be the default
in 5.10 and onwards". I think yet another environment variable
can do. PERL_5_10_ISH for example. Detailed warnings will be
wanted by developers, so they could set this variable while they
are debugging, and leave it off in production. The main
advantage of this approach is that it will not be necessary
to modify the code to get the detailed warnings.
