Someone told me not that long ago that the next big thing in computing are Regular Expressions.
Not needing such things in what I do using computers I thought, "Why, surely it is AI?"
Then I joined here and seeing you guys using them gobsmacked me. I had no idea how important BREs and EREs were until coming on here.

However a tool like that makes them easy to understand.

(Whilst in Perl mode I will learn how to use Perl's REs.)

Thanks Ravinder, great find...

NAME
Test::BDD::Cucumber - Feature-complete Cucumber-style testing in Perl VERSION
version 0.11 DESCRIPTION
A sane and complete Cucumber implementation in Perl QUICK LINKS
Cucumber on Perl on MetaCPAN <https://metacpan.org/release/Test-BDD-Cucumber> WARNING
This is beta software, at best. The interface is unlikely to undergo major incompatible changes, but it's certainly possible. Do have a read of the Bugs and Missing section below so you're not surprised when these things don't work. In almost all cases, where the behaviour of this module is different from the real Cucumber, the plan is to move it to be more similar to that. The idea is that the first 1.0 release will be the first production release and before that, you're on your own. There are many things still to add, but I'm using it to do Real Things already. NEXT STEPS
If you are completely new to Cucumber, you'd get a pretty overview from reading our short and crunchy Tutorial. If you already understand Cucumber, and just want to get started then you should read the Step-writing quick-start guide, the documentation for our command-line tool App::pherkin, and How to integrate with Test::Builder. If you want to extend or integrated Test::BDD::Cucumber then you'd probably be more interested in our Architecture overview. TEN SECOND GUIDE TO USING THIS IN YOUR CI ENVIRONMENT
Don't use the command-line tool, App::pherkin. Instead, look at the How to integrate with Test::Builder document. BUGS, MISSING, AND LIMITATIONS The following things do not work in this release, although support is planned in the very near future: o Localization o Step Argument Transforms o Quoting in tables is broken o Placeholders in pystrings is broken o Explicit Step Outline notation doesn't work (although step outlines are explicitly supported) o Unicode support is probably a bit ropey o Pherkin isn't really fit for purpose yet CODE
