| Util | <@!297037173541175296> We more reasonably check for membership in a hash by just looking the key up in the hash. | 05:13 | |
| In your code, this neatly dovetails with the need in the next line to use the looked-up value. | |||
| Also dovetailing, an `if` statement can alias the result of its condition, and you want a "normal" list, so how about: | |||
| constant $basis-postfix = 'Foo'; # Added to make example compile | |||
| my $choice = 3; # Added to make example compile | |||
| constant \choices = { | |||
| 1 => ('old', "old_$basis-postfix"), | |||
| 2 => ('new', 'old'), | |||
| 3 => ('new', 'old', "old_$basis-postfix"), | |||
| }; | |||
| if choices{$choice} -> @meld_params { | |||
| run 'meld', |@meld_params; | |||
| ``` | 05:15 | ||
| constant $basis-postfix = 'Foo'; # Added to make example compile | |||
| my $choice = 3; # Added to make example compile | |||
| constant \choices = { | |||
| 1 => ('old', "old_$basis-postfix"), | |||
| 2 => ('new', 'old'), | |||
| 3 => ('new', 'old', "old_$basis-postfix"), | |||
| }; | |||
| if choices{$choice} -> @meld_params { | |||
| run 'meld', |@meld_params; | |||
| } | |||
| else { | |||
| say "Choice $choice was not valid. Please choose from {choices.keys.sort.join(',')}"; | |||
| } | |||

| Nemokosch | You know, I'm not sure how much that check was meant for the hash. It was more for the type of the choice (and there is only this one type so far) | 06:46 | |
