This behaves as expected:

$ ./perl -Ilib -we 'my $y if 0; my $y'
Deprecated use of my() in false conditional at -e line 1.
"my" variable $y masks earlier declaration in same scope at -e line 1.

If I accomplish the same thing inside a subroutine signature, I get the wrong warning:

$ ./perl -Ilib -wE 'use experimental "signatures"; sub foo($x=0 && my $y, $y=1) {}'
Deprecated use of my() in false conditional at -e line 1.
"state" variable $y masks earlier declaration in same scope at -e line 1.

There is no state variable there.

I get the same results from 5.20.1 to 5.25.3.
