Yeah, I'm with Dave on this. Keeping it as a lexically-scoped one makes
the model simpler for users to understand, writers to document, and
porters to implement.
It already justworks with code written in this style:
package My::Package::Name;
use v5.40;
or
use v5.40;
package My::Package::Name;
I am willing to bet that >99% of perl files ever encountered are of one
of these two forms.
In the tiny cornercase that people use a toplevel brace structure for
their entire file; a.la.
package My::Package::Name {
use v5.40;
}
then maybe we just tell them "hey, don't do that. There's no need to".
That structure does also give people a real valid escape hatch in case
they genuinely did not want that feature.
Also I suspect this is the only way it'll work to not upset the "concat
all the .pm files into one script" fatpackers.
