<![...]> does not match at end of string

[moritz]

< pmichaud> rakudo:  say ?("abc" ~~ / 'abc' <![ ( \\ ' \- ]> /)
<+p6eval> rakudo 2c8bb8: OUTPUT«0?»
< pmichaud> looks like a bug with <![...]>
< moritz_> should <![...]> be the same as <!before <[...]> > ?
< pmichaud> essentially, yes.
< pmichaud> it's a zero-width negated match
< pmichaud> rakudo:  say ?("abc" ~~ / 'abc' <!before <[ ( \\ ' \- ]> >/)
<+p6eval> rakudo 2c8bb8: OUTPUT«1?»
< moritz_> pmichaud: want me to submit a bug report for the regex thing?
< pmichaud> moritz_: sure, it's an nqp-rx bug.  I've found the bug, I'm
            trying to figure out how to fix it.
