Re^2: regex catch pattern that doesn't contain a pattern

I agree that the OPed regex will match and capture the first empty string it finds (i.e., the one at the beginning of the string), but is YAPE::Regex::Explain at all valid for constructs such as (?<NAME>pattern) introduced with Perl version 5.10?

Give a man a fish: <%-(-(-(-<

but is YAPE::Regex::Explain at all valid for constructs such as (?<NAME>pattern) introduced with Perl version 5.10? Nope. According to the POD (LIMITATIONS): There is no support for regular expression syntax added after Perl version 5.6, particularly any constructs added in 5.10. But, it is valid for `.*?`	[reply] [d/l]
