[Haskell-cafe] I think someone had a complicated program to use brackets for array indexing - is it possible to use a DSL for this?

[Tikhon Jelvis]

You could make myArray a function that takes a list as an input. Of course,
all your other array functions have to account for this too. A potential
advantage is that this approach leaves the underlying array type abstract,
so you could mix and match different data structure on the backend.
(IntMap, Array, Vector… etc.)

A disadvantage is that this is non-standard usage which could be confusing
to people and there's no way I know of to statically ensure the list passed
in always had one element. That is, myArray [1, 2] would be legal and
result in a runtime error.

I don't know of a way to do it while using a normal array type directly.
