Not sure which way is right or desirable, but if possible would be good to have a consistency between the two:

19:32 |   | m: my Int %h; %h<foo> := rand; dd %h
-- | -- | --
19:32 | camelia | rakudo-moar 1c4eebe52: OUTPUT: «Hash[Int] %h = (my Int % = :foo(0.9608381618766769e0))␤»
19:32 | Zoffix | m: my Int @h; @h[2] := rand;
19:32 | camelia | rakudo-moar 1c4eebe52: OUTPUT: «Cannot resolve caller BIND-POS(Array[Int]: Int, Num); none of these signatures match:␤    (Array:D $: int $pos, Int \bindval, *%_)␤    (Array:D $: Int:D $pos, Int \bindval, *%_)␤  in block <unit> at <tmp> line 1␤␤»

You can re-bind a non-Int to Int-parametarized Hash, but you can't do the same with Arrays because BIND-POS is typed to parametarized type.
