Comment (by dd32):

 Although micro optimizations can add up, given these are not called
 repetitively on each pageload I think we can deal with the function call
 overhead for more standardised code.

 If we want to retain the no-comma-seperator behaviour, we simply need to
 pass the array in, as in: `wp_parse_id_list( (array) $q['category__in']
 );`
