| camelia | 3 => 4 | ||
| lizmat | m: sub pear(Pair $_) { say "{.key} => {.value}" }; pear(a => 4) | 13:50 | |
| camelia | Too few positionals passed; expected 1 argument but got 0 in sub pear at <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| lizmat | one of the reasons I think named arguments should always be specified with the colonpair syntax | 13:51 | |
| avuserow | Yeah I see what you mean. I've run into a few issues with trying to pass Pairs positionally. | 14:03 | |
| Nemokosch | the colonpair syntax wouldn't help with this | 14:05 | |
| m: sub pear(Pair $_) { say "{.key} => {.value}" }; pear (a => 4) | |||
| Raku eval | a => 4 | ||
| Nemokosch | no matter how funny it seems, the extra space does help with it | 14:06 | |
| avuserow | m: sub pear(Pair $_) { say "{.key} => {.value}" }; pear((a => 4)) | ||
| camelia | a => 4 | ||
| lizmat | Nemokosch that's fatarrow syntax, :a(4) would be colonpair syntax | ||
| avuserow | It's the parens around the Pair that forces it to be positional. | ||
| Nemokosch | yes, I know. And both syntaxes are treated the same way. | 14:07 | |
| and that's only right actually | |||
| lizmat | right, except 3 => 4 is *not* treated as a named, while it still is fatarrow syntax | ||
| Nemokosch | 3 => 4 is conceptually bizarre. The name "pair" doesn't properly hint that this type isn't meant for things like that | 14:09 | |
