In C/C++ the `static` here is used to avoid the array being

the same thing, no? So if I have an array of constants in a
function that I need to be accessible to a template at compile
time, and I (for obvious reasons) don't want to be initialized
at every function call, do I have to declare it `static
immutable`?
A static variable is still a runtime variable. It's effectively
the same as declaring a variable outside of the function scope at
module scope, except that it's visible only in the current scope
and the function name gets mangled into the symbol
int i;
void foo() {
static int j;
}
j is no more a compile-time value than i is. If you want an array
of constant values available at compile-time, then you need to
declare the array as immutable.
