| nHail | I'm calling this on a list which may or may not have an even number of elements: .map:{$^a~$^b~' '}. Is there a way I can tell it a fallback value for $^b in case there is an odd number? | 18:38 | |

| rf | One sec nHail I think I did this exact thing once | 18:54 | |
| I did this with .map: sub ($a, $b = 'fallback') { $a ~ $b }; | 19:03 | ||
| nHail: ^ | |||
| nHail | Ah, thanks. | 19:04 | |
| lizmat | -> $a, $b? { ... } | ||
| rf | ^ that is nicer! | ||
| lizmat | doesn't need to be a sub | ||
| although a default may be better if you're concatenating | |||
| -> $a, $b = '' { ... } | |||
| rf | -> $a, $b? { $a ~ ($b // 'abc') }; | 19:05 | |
| nHail | Tried this, says $a is not defined | 19:09 | |
| might be something else though | |||
| Got it now, thanks! | 19:15 | ||
| rf | Awesome! | 20:01 | |
