Couple more glitches in the same area:

14:59 	Zoffix 	m: my $z:{:42foo}
14:59 	camelia 	rakudo-moar 26522e8ac: OUTPUT: «5===SORRY!5=== Error while compiling <tmp>␤You can't adverb $z␤at <tmp>:1␤------> 3my $z:{:42foo}7⏏5<EOL>␤»
14:59 	Zoffix 	m: my \z:{:42foo}
14:59 	camelia 	rakudo-moar 26522e8ac: OUTPUT: «===SORRY!===␤Cannot find method 'ast' on object of type NQPMu␤»
