Looks like FastTransforms and GenericFFT need updating

Can we just use

Suggested change
$f(x::AbstractArray) = $f(x, ntuple(identity, ndims(x)))
$f(x::AbstractArray) = $f(x, Base.OneTo(ndims(x)))

? Maybe that already fixes constant propagation? It would be less breaking (I think) and should also be more efficient if ndims(x) is large.

I don't think this necessarily fixes the issue without the compiler propagating ndims(x) as a constant.

Regarding large ndims, IIUC Tuples are performant till a length of 32, and it's uncommon to have arrays with that many dimensions. In any case, this could be an optimization for ndims(x)<4, which is perhaps the common case.

I fully understand and sympathize with your concern about breakages. I'll see if the direct dependants can be fixed first so that they accept arbitrary regions, before this is considered
