Personally I find that `open(my $fh, '<', "$file_path") or return 0;` [download] is much less readable than `open(my $fh, '<', $file_path) or return 0;` [download] With the former one is forced to ponder why the author has enclosed nothing more than a single scalar in double-quotes. Perhaps `$file_path` isn't really a scalar but is instead some path object requiring stringification. So then we have to go looking for the declaration of `$file_path` and assignments to it, etc. ... only to find that it's a just a plain string after all and the double-quotes are superfluous. Editing is an art for sure but cutting for clarity is one of the easiest tasks.	[reply] [d/l] [select]

Nothing to do with constants. They are always strings, just quoted or not. You don't need to quote them when in use as hash key names. The way forward always starts with a minimal test.	[reply]
