base is part of the type. polynomial is just a 'recipe' for a
type,
the real struct would be Polynomial!(0), Polynomial!(1), etc.
Note
that Polynomial!0, Polynomial!1, ... are all different types.
Yes, that's what I intend.
Being part of the type means it's defined only at compile-time,
you
cannot use a runtime value (like 'x') to initialize it.
Note that with your current code, `base' is not visible outside
Polynomial. You can alias it to a field to make it visible:
struct Polynomial(uint base)
{
alias b = base; // b is visible outside (but set at
Ah, ok. Thank you!
compile-time !)
...
}
You can create one like this:
Polynomial!2 poly;
poly.N = [0,1,0,0,1,1];
Ok, now I remember, struct doesn't need an explicit constructor.
(in this case)
