<lizmat> expecting any of: unspace
<lizmat> but there is a an unspace there !
<lizmat> :-)
<masak> yeah, but after that :P
<masak> r: "OH HAI"\      \     .say
<p6eval> rakudo ffe441: OUTPUT«===SORRY!===␤Confused␤at

<masak> *that*, however...
* masak submits rakuodbug

So, my complaint (and lizmat's) is that Rakudo says it expects unspace
in the error message, when unspace is what it (correctly) chokes on.
