in reply to How to count substrings in an array?

Edit: forum glitch? As is evident from the title this should have ended up here

The "goatse operator" can make this a bit shorter and faster: $count =()= $string =~ /RE/; counts the number of matches in $string, so

my $count; for(@array) { $count +=()= /RE/g; }
does what you want. It evaluates the regex in list context so it returns the list of matches and then forces it to scalar context without assigning the list anywhere.
