Method resolution still searches inside bareword handles despite `no feature "bareword_filehandles"` · Issue #19426 · Perl/perl5 · GitHub

use v5.35;
use Future;
{ use feature 'bareword_filehandles'; open Future, "<", "/dev/null"; }     
my $f = Future->done(123);

Fails with:

Name "main::Future" used only once: possible typo at - line 3.
Can't locate object method "done" via package "IO::File" at - line 4.

This indicated that, despite the no feature "bareword::filehandles" that was in scope at toplevel, it nonetheless tried to resolve the ->done method call via that bareword handle that was previously opened earlier, taking precedence over the otherwise-expected resolve via named package.
