No, that's how I started this thread. If $pkg is, say, the string
"Foo::Bar", then it is ambiguous between the package Foo::Bar and the
I/O handle *Foo::Bar{IO}. The I/O handle meaning takes precedence,
if there is a handle of that name.
$ perl -E 'package Foo::Bar { sub say { say "Foo::Bar::say(@_)" } } open(\*Foo::Bar, ">&STDOUT"); $pkg = "Foo::Bar"; $pkg->say(123)'
123

You're thinking of "object" in the OO sense. I meant it in the looser
sense, of anything that the language can manipulate by first-class
mechanisms. It's an object in the same sense in which an (unblessed)
array is an object. We could well call it merely a "package". It would
probably end up implemented as an svtype, SVt_PVPK.
