How can I tell if a variable is a FileHandle?

[peterkayatwork]

I want to be able to tell if a variable is a FileHandle as opposed to a
string, hash, whatever. I know perl will tell me that it's a Glob:

If I do:

----code:
my $fh=\*STDIN;

print "Have [$fh]\n";
----end of code

it tells me
Have [GLOB(0x10131870)]

Thanks, perl.

If I do an "isa" to see if I've got a glob, what else could it be
besides a FileHandle?

Better yet, is there a more elegent way to tell if I've got a
FileHandle or a String?

See the current thread "GLOB vs IO::Handle"
