As is its wont, in just two lines of code, Perl 6 does something that would have taken like 20 lines in Python and 100 lines in Java in my guesstimation: it takes in all words in the built-in English word file (/usr/share/dict/words), one per line, and prints all words that match the regex `^ .e.rl ---

First taste of Perl 6

Woohoo! Running it is believing. Now I believe Perl 6's regex voodoo is a reality, not just a figment of my imagination.

. Turns out there are two.

One apparent convenience Perl 6 has over Perl 5 is that the whitespace inside a regex pattern is by default ignored, to enhance readability. Another feature not illustrated here is that single-line comments (beginning with the # character) can be embedded in regex too. I really appreciate this effort to encourage more regexing!

In researching this mysterious French word that sounds like /ʁe "ɡlo/, I pulled this from the web, from a French-French dictionary site:
