The core should localise it, to match the treatment of BEGIN blocks.
Fixed in commit b6f3718f1b3218256c962a8f46e747048228d196.

It's tricky to test.  Filter::Util::Call is a cpan/ distro with its own
tests, and there's not much access otherwise to filtering from pure Perl.
But I found that hook subroutines in @INC are also affected by this
problem, though differently, so I put in a test that uses that mechanism.
