Only Int64 works for the length of the array

[tautomer]

This might be a trivial problem, since the defualt type of integer is Int64.

using StaticArrays
n::Int8 = 20
x= MVector{nw, Float64}(undef)

returns

ERROR: ArgumentError: Static Array parameter Size must be a tuple of Ints (e.g. `SArray{Tuple{3,3}}` or `SMatrix{3,3}`).

while

using StaticArrays
n = 20
x= MVector{nw, Float64}(undef)

works fine.

I think in the Integer supertype, only Int64 is accepted. Is there any particular reason for this?

For the type parameters, I believe the N in NTuple{N} should be an Int, so we need to be really careful there! I don't think we can relax that one, sorry.

At an API level (for a function like similar(SOneTo(n), Float64)), possibly this should be doable. There is some residual historical confusion in the code on whether Base required Integer or Int (as this package emerged durin Julia 0.5-dev and Base itself was confused about this point for AbstractArray back then).
