<masak> ok, second iffy-related weirdness​:
<masak> m​: multi infix​:«<​:» { $^l lt $^r }; multi infix​:«!<​:» {
not($^l &lt;​: $^r) }; say "foo" !<​: "bar"
<camelia> rakudo-moar d8c834​: OUTPUT«True␤»
<masak> now watch as I perform my magic trick​:
<masak> m​: multi infix​:«≃» { $^l lt $^r }; multi infix​:«!≃» { not($^l
≃ $^r) }; say "foo" !≃ "bar"
<camelia> rakudo-moar d8c834​: OUTPUT«===SORRY!=== Error while
compiling /tmp/q8BePJqzE4␤Cannot negate ≃ because it is not iffy
enough␤at /tmp/q8BePJqzE4​:1␤------> x​:«!<​:» { not($^l ≃ $^r) }; say
"foo" !≃⏏ "bar"␤»
<masak> *exactly* the same code -- just with a Unicode operator instead!
* masak submits rakudobug

Surely if the first bit of code works, the second should, too.

From @masak

Heh; just in case someone takes a close look at that error message and is terribly confused... here's the correctly pasted one​:

<masak> m​: multi infix​:«≃» { $^l lt $^r }; multi infix​:«!≃» { not($^l ≃ $^r) }; say "foo" !≃ "bar"
<camelia> rakudo-moar d8c834​: OUTPUT«===SORRY!=== Error while compiling /tmp/weCLGmom3M␤Cannot negate ≃ because it is not iffy enough␤at /tmp/weCLGmom3M​:1␤------> ix​:«!≃» { not($^l ≃ $^r) }; say "foo" !≃⏏ "bar"␤»

That's better. Nothing to see here, move along.

From @Mouq

This appears to have been fixed at some point​:

22​:29 <Mouq> r​: multi infix​:«≃» { $^l lt $^r }; multi infix​:«!≃» { not($^l ≃ $^r) }; say "foo" !≃ "bar"
22​:29 <camelia> rakudo-{parrot,moar} 127c99​: OUTPUT«True␤»

Marking as testneeded

The RT System itself - Status changed from 'new' to 'open'

From @usev6

I added a test to S03-operators/misc.t with commit Raku/roast@deaf607dfb

I'm closing this ticket as resolved.
