Hello. This is a minimal abstraction of a part of my program:
int func(string s)
{
static int [] i = [5, 6, 7];
return i[2];
}
template temp(string s) { enum temp = func(s); }
void main() { static assert(temp!"str" == 7); }
With the above code I get:
(4): Error: static variable i cannot
Why do you declare mutable constants?

Thanks to all who replied.

It would seem that in the case of arrays, the former is preferable to the
latter, as per the para above this header:
