Sometimes it is useful to test the input against regexes. Let's try​:

Code​:
use Test;
cmp-ok �foo�, �~~�, /bar/, �Lorem ipsum.�

Result​:
not ok 1 - Lorem ipsum.

# Failed test 'Lorem ipsum.'
# at -e line 2
Regex object coerced to string (please use .gist or .perl to do that)
  in sub cmp-ok at /home/â�¦/â�¦/C712FE6969F786C9380D643DF17E85D06868219E (Test) line 243
# expected​: ''
# matcher​: 'infix​:<~~>'
# got​: 'foo'

It �works�, but it attempts to turn a regex into a Str.

The problem is here​: https://github.com/rakudo/rakudo/blob/90a0f2e09ef7a74bfb5a8295fa2737f22bd4e07f/lib/Test.pm6#L245-L247

�.gist� should work better in this case, but I'm not sure if it will affect the output significantly in other cases�

I'm using regexes a lot for whateverable tests (e.g. https://github.com/perl6/whateverable/blob/0301ef4bd2e88536b775db219d19084c092e24ca/t/evalable.t#L84-L88 ). Currently it is doing something completely different underneath (due to now-fixed RT #​129192), I wanted to change it to regular cmp-ok.

".gist" is probably the wrong answer in this case.

my @​got = ‘one’, ‘two three’; say @​got # OUTPUT​: [one two three]

↑ Not very useful

It “works”, but it attempts to turn a regex into a Str.

“.gist” should work better in this case, but I'm not sure if it will
affect the output significantly in other cases…
