<masak> new bug? :)
<moritz_> it seems so, yes
* masak reports
<pmichaud> rakudo:  grammar A { token ws { 'a' }; rule b {x y}; }; say
'xab' ~~ m/ ^ <A::b> $/

<pmichaud> hmm.
<masak> ah, so it was the lower-case 'a'?
<pmichaud> yes, because nothing was defined as 'a'
<masak> still shouldn't throw that error.
<pmichaud> agreed, should throw a better one.
