| camelia | done | ||
| lizmat | m: sub ponder { next FOO }; FOO: for (1..3) { ponder; .say }; say "done" | 10:05 | |
| camelia | ===SORRY!=== Error while compiling <tmp> Variable '&FOO' is not declared. Perhaps you forgot a 'sub' if this was intended to be part of a signature? at <tmp>:1 ------> sub ponder { next ⏏FOO }; FOO: for (1..3) { ponder; .say }; |
||
| lizmat | m: FOO: for (1..3) { next FOO; .say }; say "done" | ||
| camelia | done | ||
| Nemokosch | now I'm looking up roast if this case was ever planned for | 10:06 | |
| it seems fairly intuitive that next/last stuff should behave like return | |||
| lizmat | next / last / redo are control exceptions | 10:08 | |
| m: CONTROL { say .^name }; next | 10:09 | ||
| camelia | CX::Next next without loop construct in block <unit> at <tmp> line 1 |
||
| lizmat | any loop construct basically sets up a "catcher" for such exceptions | ||
| Nemokosch | I don't think the implementation should matter too much for the expectations | 10:10 | |
| A Block acts inlined, a Sub is context-insensitive | |||
| lizmat | which is why it is able to say "next without a loop construct" because there's an outer CONTROL block that catches them and puts out the message | ||
| well, I guess you could call that behaviour another Perl heritage | 10:11 | ||
| Nemokosch | actually this doesn't even sound too bad | 10:13 | |
| subs need a CONTROL handler by default, sounds about fixed? | |||
| lizmat | except from an optimization point of view | 10:14 | |
| BTW, do you want a warning or throwing an exception ? | 10:16 | ||
| anyways, I think this could be handled easier with a check at the receiving side, checking the outer lexical sub scope: if different warn or throw | 10:17 | ||
| Nemokosch | > CX::Nextnext without loop construct | 10:18 | |
| I think this would fit perfectly for these scenarios as well | |||
| lizmat | still, that also would impose a performance penalty, but at least it would be for the use of next/last/redo | ||
| afk& | 10:19 | ||
| Nemokosch | if somebody wants to live on the edge, they can use Block | ||
| I never knew there was goto in Raku lol | 10:41 | ||
| once RakuAST is ready, it will become much easier to search code for certain structures | 10:58 | ||
| by the way, from optimization point of view - in RakuAST, it will be easy to detect if this "guarding handler" is necessary at all | 11:02 | ||

| One more thing: I wonder how the specification could handle a change like this. First off, it's not obvious whether this is a change because it doesn't seem to be present in the spectests. But since code might depend on it (and it does, confer doc tests), let's say it is a design-level change. | 11:32 | ||
