More importantly, the map version will be correct in the case where the substitution fails (because the element contains no comma characters). In the grep version, a failed substitution will cause the grep condition to evaluate to false, and the element will be filtered out.

FWIW, here’s my variation on the map body, adding the /r modifier to the substitution:

$i = 0;
$line2 = join '', map { $i++ % 2 ? s/,/ /gr : $_ } split /"/, $line;
