Hi Fellas,

I'm looking for the most succinct and elegant way to get the number of times a regexp matches, using only one statement. I don't want to use a loop, or any unnecessary variables, and as always, efficiency counts. At first, I assumed one could simply scalar a list returned by the match, but using scalar forces the regexp itself into scalar evaluation mode, so the following won't work: 

$count = scalar ($str =~ m/pattern/g);

A few working solutions from the CB were: 
$count = scalar map {1} ($str =~ m/pattern/g);
$count = scalar @{[$str =~ m/pattern/g]};
$count = ($str =~ s/pattern/$1/g);

But these seem either too unintuitive or inefficient for such a common task. Is there a better way?
