p6eval nom 48af8c: OUTPUT«===SORRY!===␤Variable $a is not
declared␤at eval_0:1␤»
masak huh!
jnthn nom: x ~~ /:my $a = 42; { say $a } ?/
p6eval nom 48af8c: OUTPUT«42␤»
jnthn oh...
jnthn it's eval'ing that regex, no?
jnthn masak: if you can golf that one it'd be nice...
masak gotcha.
masak I'll golf it and then RT it.
masak nom: '' ~~ / :my $a; { '$a' } /
p6eval nom 48af8c: OUTPUT«===SORRY!===␤Variable $a is not
declared␤at eval_0:1␤»
masak golf'd.
