I'm reading the part about adverbs and precedence, and I'm thinking that adverbs are probably just complicated enough for the average programmer not to grok them. :) 11:01
a bit like variant sigils in Perl 5.

moritz no: We have very clear rules of which literals produce what types 17:18
and since for example Num and Int arithmetic produce different results, it must be possible to write an integral Num 17:19
timotimo right
moritz: ack/nak on running the jvm spectests on r-regex_optimizer?
moritz timotimo: I'll start another spectest run 17:20
timotimo thank you! :)
BenGoldberg Speaking of regex optimization ... will there be something like perl5's 'study' operator, or is that for the distanct future? 17:26
timotimo please explain what that does to me? i never did any perl5
BenGoldberg It did some analysis of a string, so that future regex matches on that string ran faster. 17:28
timotimo ah, ok
sounds like a fun project
but probably for much later :)
BenGoldberg distant future, then :) 17:31
timotimo well, it really depends; rakudo development has a few people who are not focusing their efforts optimally (me, for example) 17:32
optimally, we would always be doing the most pressing bottleneck and the most interesting feature, but I tend to go around looking for fun optimizations to do and lacking features that bother me directly
moritz timotimo: now I get "nqp-j is too old" 17:34
timotimo er, whoops. i think you should be able to just rebase the nqp branch on current master
moritz I can also locally merge the nqp branch into master
timotimo sure
moritz does, and recompiles NQP 17:36
timotimo: should I do the same for the rakudo branch?
timotimo i'm trying it with a rebase, too 17:37
the rakudo branch is already rebased on newest nom, but you should just be able to merge nom into the old version of that branch
it's just a two-line change or something

moritz with qqx it'll try to interpolate the $? or some parts of it in perl code 20:49

I wonder if shell/run is experiencing the same issue, or if this is a result of using qqx// ... 21:16
