Description
The Changing use VERSION while another use VERSION is in scope is deprecated, and will become fatal in Perl 5.46 warning triggers in cases that don't make sense. It looks like the use VERSION context sometimes leaks into used modules that use string eval.
This affects CPAN modules like Data::Munge: https://rt.cpan.org/Ticket/Display.html?id=152677
Steps to Reproduce
Contents of Foo.pm:
package Foo;
use v5.14;
eval 'use v5.14';
1This runs normally; no warnings:
$ ./perl -I. -e 'use Foo;'
$
This triggers a warning, but only for the eval'd code; the main module code is fine, apparently, even though both try to use v5.14:
$ ./perl -I. -e 'use v5.20; use Foo;'
Changing use VERSION while another use VERSION is in scope is deprecated, and will become fatal in Perl 5.46 at (eval 1) line 1.
Expected behavior
No warnings.
