roguerakudev So I have an enum for "packet subtype", where the values are going to get packed into a single byte along with a packet type, and I want to be able to reuse values across different keys, which is totally possible, but I then want to be able to recover the correct enum value from a plain integer for incoming packets 03:59
my thought was to have a For[PacketType $FOR] { ... } role which I could mix into the integer values, e.g. 0b0000001 but For[PacketType::Whatever] 04:00
however, that results in a somewhat cryptic error, "Incompatible MROs in P6opaque rebless for types Int+{For[PacketType]} mixin and PacketSubtype" 04:01
I was wondering if anyone had a way around this or a different idea for a nice way to achieve what I'm trying to achieve 04:02

camelia "answer"
gfldex @roguerakudev If that ^^^ doesn't work for you, I would suspect an only Rakudo version.

tbrowder__ ok, i just released an updated Abbreviation with default action to provide a regex "alternation" (not a junction) for a single word. 12:47
for example: my $a = abbrev "Args"; say $a; # OUTPUT: A|Ar|Arg|Args 12:49
i 12:52
arg, can't even remember proper module name, plural: Abbreviations 12:54

roguerakudev gfldex: yeah, sure enough I'm on a somewhat old rakudo version on this machine 19:54
Hm, but even on 2023.12 I'm still getting the same error 19:57
antononcube I am very curious about anythin use lib related.
roguerakudev oh, but not if I have only one enum value listed in the enum
very interesting...
it's not a weird precedence thing either, because even with parens to make it explicit, same result 19:59
m: role R[$a] { has $.type = $a }; enum foo (bar => 42 but R['answer'], baz => 41 but R['question']); dd bar.value.type;

roguerakudev You know you're really programming when you hit compiler bugs like this :^) 20:00
