I kind of expected that suffixing the classname with "::" would help (which
is already needed if you have a sub with the same name as the class:

  $ perl -E 'package foo; sub bar { say "baz" } package main; sub foo { "xyzzy" } foo->bar'
  Can't locate object method "bar" via package "xyzzy" (perhaps you forgot to load "xyzzy"?) at -e line 1.

  $ perl -E 'package foo; sub bar { say "baz" } package main; sub foo { "xyzzy" } foo::->bar'
  baz

But it doesn't help with the "filehandles take priority" case:

  $ perl -E 'package foo; sub bar { say "baz" } package main; BEGIN { fileno foo } foo::->bar'
  Can't locate object method "bar" via package "IO::Handle" at -e line 1.

I wonder if it should...
