camelia Type check failed in assignment to $!E; expected E but got E (E::V1)

_________ "expected E but got E" ;D
lizmat just blogged again: dev.to/lizmat/a-practical-example-...kuast-18jk 10:01
thundergnat lizmat++  BTW  instalment -> installment, RakUAST -> RakuAST 10:14
lizmat instalment is UK spelling, installment is US 10:14
guifa Brits hate Ls, Americans hate Us 10:15
lizmat anyways, fixed: thundergnat++ 10:16
timo we can use RakUAST for any user-added ast bits, kind of like the linux subsystems "uinput" :D 10:17
lizmat that's what macros are all about, no?
timo i guess so yeah 10:18
Voldenet it would be nice if `use RakuAST::Regex` could be done, so `CharClassEnumerationElement::Character, Assertion::CharClass and CharClassElement::Enumeration` could be directly used 11:24
lizmat Voldenet: I think we will see some official and semi-official shortcuts 11:25
I'm not sure "use RakuAST::Regex" would help: I would be in favour of moving pragmas from "use" to a dedicated such as "pragma foo" and "pragma foo :off" 11:27
in fact: in RakuAST, pragmas already have their own class: 11:29
m: say Q|use strict|.AST.statements.head
Voldenet `import RakuAST::Regex as Rx` ;)
camelia RakuAST::Pragma.new(
off => 0,
name => "strict"
)
lizmat Voldenet: you can already do that with a constant?
my constant Rx = RakuAST::Regex ??
Voldenet neat 11:31
in that case I'm guessing the code can be massively shortened 11:32
being able to import whole RakuAST and RakuAST::Regex would be easier to work with locally, but `my constant R = RakuAST; my constant Rx = R::Regex;` would look more pleasant 11:36
lizmat: btw pre-cursor -> precursor 11:38
lizmat thanks, fixed 11:39
jdv lizmat: cool rakuast posts 14:56
Xliff_ elcaro: It may not be exactly what you want, but you could always .encode the Str when you get it. 15:16
How difficult would it be to implement COMPOSE? 15:19
Xliff_ I am currently hacking away with a .Init method, but it would be nice to have a formal mechanism to properly incorporate roles into an object. Consider: role A { has $.a; method value { ... }; submethod COMPOSE { $!a = self.value / 2; }; }; class B { has $.b is built; method value { $.b }; }; my $b.new(b => 32); $b does A; 15:22
Xliff Is there an idomatic way of saying I would like an array containing the 100 values between 5 and 255? 17:39
I think this would be analogous to the Javascript map function. 17:40
lizmat which 100 values between 5 and 255 ? 17:41
that'd be 201 values ?
Xliff Or not...
lizmat well, 199 maybe then ?
Xliff No. Take 5..255 and get an array of 100 values between the two representing the stops.
lizmat (5..255).pick(100) 17:42
Xliff Nope. That's random. I want a linear function.
And my brain just doesn't want to Math right now.
lizmat I don't understand the question then 17:43
