These are now the same (both in nom and glr, even)
12:10 < [Coke]> m: sub foo(@a) { @a[1] = "NOES" }; my @a = <OH HAI>; foo(@a);
say ~@a
12:10 <+camelia> rakudo-moar 47ddca: OUTPUT«OH NOES»
12:10 < GLRelia> rakudo-moar 345953: OUTPUT«OH NOES»
12:11 < [Coke]> m: sub foo(@a) { @a[0, 1] = <OH NOES> }; my @a = 0, 1; foo(@a);
say ~@a;
12:11 <+camelia> rakudo-moar 47ddca: OUTPUT«OH NOES»
12:11 < GLRelia> rakudo-moar 345953: OUTPUT«OH NOES»
Closable with tests?
