NTuple requires the first type parameter to be Int64

[musm]

Is there any reason why it's restricted to Int64 ?

I.e.

julia> NTuple{Int32(3),Float32}
ERROR: TypeError: in Vararg, in count, expected Int64, got Int32

Types don't have "sizes," only values have sizes (when you do sizeof(NTuple{N,Float32}) it reports the size of the corresponding value). So there's no advantage in supporting it, and to the contrary supporting only Int avoids nasty "how come these look exactly the same but aren't the same type?!?" train wrecks.

What are you trying to do? Let me guess: this comes up in supporting data types saved via HDF5/JLD/JLD2 on machines with different word sizes? It would be best to normalize the reconstructed types so that N is always Int.

Thanks for the reply. Makes sense and yes that was how this came up.
