in thread $1 not "freezing" in an addition

I see no reason perlcritic couldn't do the same

PPI won't descend into functions or methods and can't descend into XS. You can only get so far with static analysis when trying to find all modifications of a global variable at or below your current call site.

Doesn't stop perlcritic from doing the descending, or running B::Xref

and can't descend into XS

descending into XS is not insurmountable either

You can well get pretty far I tell you what

who says we have to find them all? or even descend? or even all globals?

I see no use case for relying on the behaviour we see here , so IMHO it seems like a very safe low level warning for every  $global ... func to be turned into  "$global" ... func , esp for $1

How is P::C to descend into code that's not loaded until runtime?

How is P::C to descend into compiled code that's not loaded until runtime and for which the source code is not available?

How do you know you've caught every global? How do you know stringification is desirable?

It could, wait for it, load the code

do the scandeps dance

not do anything at all

Who said P::C is supposed to do it ?

Clearly stringification of $1 is undesireable -- I am humbled by your logic
