Descriptionreset() works with some core variables (e.g. $0, $^X), but not others (e.g. $|, $1, $^W).
Steps to Reproduce
$ perl -wE '$| = 1; reset "|"; say $|'
1
$ perl -wE '"hello" =~ /(.*)/; reset "0-9"; say $0, $1'
Use of uninitialized value $0 in say at -e line 1.
hello
$ perl -wE 'reset "\x01-\x1f"; say $^X, $^W'
Use of uninitialized value $^X in say at -e line 1.
1
Expected behavior
I would've expected all of these variables to be reset to undef, or if that's not possible (eyeing $| in particular), an error or warning to be generated.
