| jnthn | nine: Wow, that's some progress :-) | 11:18 | |
| timo | i wonder when the right time would be to start building something on top of rakuast that's not "make tests work" | 11:35 | |
| nine | My guess at this point: just a couple of months after you joined building something that's "make tests work" ;) | 11:36 | |
| lizmat | an intermediate project could be rewriting the "assuming" logic in RakuAST ? | 11:37 | |
| timo | :D | 11:59 | |
| jnthn | I think most ideally with assuming we'd have some role mixed in wrap-style that marks out the argument transformation, and use new-disp to do the argument insertion (because that's exactly what new-disp is good at :)) and only lazily produce a signature if it's ever introspected. | 12:05 | |
| That way, the calls to such functions would spesh into pulling the assumed arguments out of a constants table and then a normal boring call | 12:06 | ||
| lizmat | jnthn: are you saying this should be independent of RakuAST ? | 12:07 | |
|

| jnthn | lizmat: RakuAST would be a decent way to produce the transformed signature | 12:09 | |
| lizmat | ah, ok, *phew* :-) | ||
| jnthn | But at least on MoarVM it's a pity to not make use of new-disp to do the argument insertion | ||
| lizmat | so I guess we would keep the old code for the other backends? | 12:11 | |
| jnthn | I think for other backends RakuAST could be used to straight up produce the wrapper | 12:12 | |
| (including signature) | |||
| Hm, wrapper is a bad name for it. The delegator perhaps. :) | |||
| Most of the work *is* producing the signature anyway | 12:13 | ||
| lizmat | that makes it sound like new-disp is a disadvantage / more work ? | ||
| jnthn | More work, but producing the signature lazily will be way faster for cases that never introspect, just call, and the calls will be somewhat faster if new-disp can just have it as an argument capture rewrite | 12:14 | |
| As with many things, one doesn't *have* to teach the VM about them via new-disp, but doing so can bring significant speedups :) | 12:15 | ||
| lizmat | and yet another Rakudo Weekly News hits the Net: rakudoweekly.blog/2022/07/04/2022-...re-videos/ | 12:32 | |
| nine | lizmat: brilliant image choice :) | 12:35 | |
| lizmat | thanks... :-) | ||

| jnthn | lizmat++ | ||
| nine | Did you have this use case in mind when taking it or did it occur to you later? | 12:37 | |
| lizmat | I had it in mind | ||
| other than cropping and a little colour correction, no other tampering was performed :-) | 12:38 | ||

| timo | i wonder how many (if any) signatures we have serialized in the core setting that would be saved if assuing created signatures lazily | 21:12 | |
