The fact that you sort of can't easily index tuple of 3 ints
as a fixed array of 3 ints is a clear indication of a tendency
that I find disturbing.
But there is a reason for this: tuple/structs can contain
heterogeneous type whereas array contains only homogeneous
type..
So if you want to index a tuple/struct of say {int,int[128]}
you have to build an array of pointers to these index, possible
but clearly not free..
So I wouldn't agree that tuple/struct are 'trivially
substitutable' to array..
No. A tuple is by definition an ordered, finite sequence of
elements. There is no problem to index that.
tuple a = {
5;
true;
0.1
}
is(typeof(a[0]) == int)
is(typeof(a[1]) == bool)
