meth (Array: array)[Index₁: any, ...]: array

Returns a sub-array of Array sharing the underlying data, indexed by Indexᵢ. Dimensions are copied to the output array, applying the indices as follows:

If Indexᵢ is nil or * then the next dimension is copied unchanged.
If Indexᵢ is .. then the remaining indices are applied to the last dimensions of Array and the dimensions in between are copied unchanged.
If Indexᵢ is an integer then the Indexᵢ-th value of the next dimension is selected and the dimension is dropped from the output.
If Indexᵢ is an integer::interval then the corresponding slice of the next dimension is copied to the output.
If Indexᵢ is a tuple[integer, ...] then the next dimensions are indexed by the corresponding integer in turn (i.e. A[(I, J, K)] gives the same result as A[I, J, K]).
If Indexᵢ is a list[integer] then the next dimension is copied as a sparse dimension with the respective entries.
If Indexᵢ is a list[tuple[integer, ...]] then the appropriate dimensions are dropped and a single sparse dimension is added with the corresponding entries.
If Indexᵢ is an array::int8 with dimensions matching the corresponding dimensions of A then a sparse dimension is added with entries corresponding to the non-zero values in Indexᵢ (i.e. A[B] is equivalent to A[B:where]).
If Indexᵢ is an array::int32 with all but last dimensions matching the corresponding dimensions of A then a sparse dimension is added with entries corresponding indices in the last dimension of Indexᵢ.

If fewer than A:degree indices are provided then the remaining dimensions are copied unchanged.
