Description
When the bareworld_filehandles feature is disabled (e.g. under use v5.35;), package method calls are also forbidden where a bareword filehandle would be.
Steps to Reproduce
$ perl -le 'no feature "bareword_filehandles"; sub foo { "foo" } print main->foo'
Bareword filehandle "main" not allowed under 'no feature "bareword_filehandles"' at -e line 1.
Execution of -e aborted due to compilation errors.
It seems to be interpreting the bareword const op under the entersub as a bareword filehandle, even though that's actually the argument to method_named:
$ perl -MO=Concise -e 'no feature "bareword_filehandles"; sub foo { "foo" } print main->foo'
Bareword filehandle "main" not allowed under 'no feature "bareword_filehandles"' at -e line 1.
-e had compilation errors.
9 <@> leave[1 ref] KP/REFC ->(end)

2 <;> nextstate(main 4 -e:1) :us,*,&,{,$,fea=6 ->3
8 <@> print K ->9
3 <0> pushmark ->4
7 <1> entersub[t1] KRS/TARG,STRICT ->8
4 <0> pushmark ->5
5 <$> const(PV "main") s/BARE ->6
6 <.> method_named(PV "foo") ->7
Expected behavior
Same as with the feature enabled:
$ perl -le 'sub foo { "foo" } print main->foo'
foo
