And what do you think *fh is.

A glob, what you should have used instead of \*fh.

You don't (*CAN'T*) bless a var; only a reference to one!

Actually, you have that backwards. I've never seen a blessed reference. You have to pass a reference to bless, but it's the var that gets blessed. Otherwise, the following would fail: 

sub foo { CORE::say "ok" }
my %h;
my $ref1 = \%h;
my $ref2 = \%h;
bless($ref1);
$ref2->foo();

How can "the reference be blessed",

I said ref would fail if the glob is blessed. 

$ perl -MScalar::Util=reftype -e'
   CORE::say ref(\*FOO);
   CORE::say reftype(\*FOO);
   bless(\*FOO);
   CORE::say ref(\*FOO); 
   CORE::say reftype(\*FOO);
