&gt; Both Perl and Go implement regexps, and neither or them compile them to native code. So I don&#x27;t get your previous comment at all.<p>Ok, I&#x27;ll try to explain.<p>People feel discouraged to use regexps in Go, because they are very slow for many typical parsing and validating cases and require extra step of compilation and all of the additional code complexity associated with that. So, people do parsing manually instead, with all of its problems. It&#x27;s not that they need that performance, almost no one does, but the whole idea behind regular expressions is not working, parsing code is still bad most of the time.
