Hello hda,

LanX has answered your question, but I was somewhat surprised by the error message (which comes courtesy of use strict;, BTW), since it appears that $fh is already declared when the die code is parsed. Deparsing shows what’s going on: or is (apparently) rewritten as unless, which places the $fh in the die clause before its declaration in the call to open:

22:56 >perl -MO=Deparse -Mstrict -we "my $file = 'x'; open (my $fh, '<
+', $file) or die qq[Can't open $fh];"
Global symbol "$fh" requires explicit package name (did you forget to 
+declare "my $fh"?) at -e line 1.
-e had compilation errors.
BEGIN { $^W = 1; }
use strict;
my $file = 'x';
die "Can't open ${'fh'}" unless open my $fh, '<', $file;

22:56 >

Hope that’s of interest,
