my @a is Array::Sparse;
@a[0,1] = <a b>;
say @a[]:v;
# OUTPUT: «(a)␤»

Changing/removing any of these factors hides the bug:

• is Array::Sparse
  • not a core Array
• list assignment to a non-zen slice
  • not list assignment to the whole array
  • not a zen slice
  • not procedural assignment to individual indices
• zen slice retrieval
  • indexing with Whatever in the forms [*] and [^*] also trigger the bug, but [0..*] and [0..^*] do not
  • not the whole array itself
  • not a slice of ranges/values whether explicitly bounded or infinite
• must be adverbed
  • all adverbs tested do show this same behavior, including :k, :v, :kv, and :p
  • not the equivalent method calls

(my @a is Array::Sparse)[2] = 1; say @a.raku produces Array::Sparse.new(1)
