    Thanks very much for this overview. I’m pin­ning it on my pinboard.

    I sug­gest chang­ing the title of this post to ​“Better Perl with sub­rou­tine sig­na­tures and type val­i­da­tion”. That’s real­ly what the post is about. It will help peo­ple find your post bet­ter, and it makes it eas­i­er for folks when they book­mark it.

    In some con­ver­sa­tion on this top­ic, I dis­tinct­ly remem­ber typ­ing how I did­n’t think it was such a prob­lem not to have sig­na­tures, that it’s not that dif­fi­cult to keep things straight.

    Well, I’ve just spent a week­end work­ing on a project and sig­na­tures would have SURELY helped as I changed the api from pass­ing around bits and pieces to pass­ing around a sin­gle data structure.

    “Can’t use string (“Pod::Parser”) as a HASH ref while ​“strict refs” in use at bin/​pmdh-​modulate line 517.”

      The good news is that with mod­ules like Type::Tiny and Params::ValidationCompiler you can intro­duce it grad­u­al­ly into your codebase.

    […] Some of the feed­back I got indi­cat­ed that there were more options to con­sid­er, so for the pre­sen­ta­tion I gave at Hous­ton Perl Mon­gers I quick­ly sum­ma­rized at the end sev­en more mod­ules from CPAN that offer these features. […]
