uzl[m] ^ When using `contains` with a regex as a needle, a list isn't coerced into a string. Is that the expected behavior? 15:11

tellable6 uzl[m], I saw jmerelo 2020-02-26T20:04:44Z in #raku-dev: <jmerelo> tbrowder: that would be OK, I think.
tobs uzl[m]: I don't think this has to do with coercing. The contains method has no candidate for a regex needle. Not on List, not on Cool and not on Str. 15:20
m: "Hello, World".contains(/Hello/, 0)
evalable6
tobs m: say "Hello, World".contains(/Hello/, 0)
evalable6 True
tobs huh?
maybe my rakudo is too old, sorry 15:21
uzl[m] In 2020.02, there are a few candidates for a regex needle
tobs: github.com/rakudo/rakudo/releases/tag/2020.02 15:23
tobs then I can only imagine that the problem is that they're not on Cool but on Str. The mechanism that turns the List into a Str ad-hoc is that the List is Cool.

uzl[m] tobs: That makes sense. I wonder if that's how it should be behave though; I'd expect the list to be turned into a string when using a regex too. Not a big deal though since you can always stringify the list before calling contains (with a regex) on it. 15:36
tobs no, I think it should work and it seems easy to add 15:37
15:37 sena_kun joined
tobs you just need the new contains candidates on Cool as well. 15:37

rjt_pl I think I'm having a brain fart. Is there a way to have positionals work in inner scopes, like my second silly example? 21:52
Obviously I can assign them to lexical (my) vars or other workarounds, but that sort of defeats the purpose. 21:53

rjt_pl Emphasis on silly example. That was just to illustrate the problem: using positionals ($^a, etc.) inside of an inner lexical scope. Is it possible? 21:58

rjt_pl Ah, the pointy block. That'll do. Thanks. 22:08
Doc_Holliwood MasterDuke: There is some room for cleverness but it does not buy you much. 22:10
MasterDuke ah 22:12
Doc_Holliwood Consider how fast the binary string grows. After a few iterations you reach 111111111 which is already bigger than most n and from there you have to brute force no mather what 22:13
so, 3000 iterations (lets say) or 3020 makes no difference

MasterDuke for $n == 30000020, starting at $n.sqrt.Int save me ~0.3s (e.g., 5.0s instead of 5.3s) 22:18

evalable6 110000100000001111100 22:22
lizmat I wonder if you could combine the .map and the .first into a single .map and a "last" 22:28

discord6 <Highlander> Yeah I don't think sqrt is right there 22:53
<Highlander> it's a bit cheesy, but you could start at ($n * 2).base(2).Int
<Highlander> wait no
<Highlander> ignore that lol, very wrong 22:54
rypervenche It's just a way to move up by one in base 2, no? I don't see how any conversion into base 2 would work in that case. I might be missing the logic though.
discord6 <Highlander> My logic was very wrong--I was thinking in reverse 22:55
<Highlander> I think maybe ('1' x $n.chars).parse-base(2) would be a safe starting point 23:00
<Highlander> It will always be less than $n * 2, which is the first place you could find a multiple 23:01
