<sorear> How does case insensitive matching work in perl 6?
<sorear> e.g. "ß" ~~ m:i/SS/
<masak> sorear: that's the syntax, so I assume you're asking about the
semantics.
<masak> oh wait, that example is tricky :)
<masak> I would be surprised if Perl 6 is spec'd to handle that.
<sorear> yes. semantics, and dark corners thereof
<sorear> yes, S05 says exactly nothing on the subject
<sorear> other than "ignores case distinctions"
<moritz_> rakudo: say "ß" ~~ /:i SS/
<p6eval> rakudo cfbeb5: OUTPUT«»
<moritz_> rakudo: say uc "ß"
<p6eval> rakudo cfbeb5: OUTPUT«SS»
<masak> o.O
<masak> German is strange.
<moritz_> it sure is.
<moritz_> masak: want to submit a bug report about inconsistency?
* masak submits rakudobug

Behavior changed:

semantics in (what I consider to be) the wrong direction. I.e. now
instead of one of two things behaving the wrong way, both do.
