this will be much better handled by a transformation
if ( $(fn{s.len}) > 62 ) {...}
Yes, using pcre_math is good when we need to perform a regular expression against a PV (which is not possible using "=~"). For example I use it to check if the RURI username matches a prefix extracted from a database:
if ! pcre_match("$rU", "^$var(client_prefix_in)") {
This works because the regular expression is compiled in runtime.
This would not be possible with "=~":
if ! $rU =~ "^$var(client_prefix_in)") {
It fails because the regular expression is compiled when parsing the config script.
