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.

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

That is, to use myArray [5] and have a DSL convert it to standard Haskell syntax
