Started work on B::AST, an abstract syntax tree representation of programs; this should help with translation to other languages. The eventual plan is to translate B::Deparse into something that takes output from B::AST. One day.
Anyway, this necessitated writing a module to turn the numeric value of an op (or SV)'s flags into text; this in turn needed a patch to Perl because the relevant function in dump.c was ignorant of some of the newer private flags. Fixed that up, and then release B::Flags to CPAN.
