Doesn't stop perlcritic from doing the descending, or running B::Xref
How is P::C to descend into code that's not loaded until runtime?
descending into XS is not insurmountable either
How is P::C to descend into compiled code that's not loaded until runtime and for which the source code is not available?
IMHO it seems like a very safe low level warning for every $global ... func to be turned into "$global" ... func , esp for $1
How do you know you've caught every global? How do you know stringification is desirable?
