• Dr.No (14/14) Jun 12 2018 I'd like help of compiler to check this:
• Adam D. Ruppe (2/3) Jun 12 2018 Only way is to make it a compile time (template) param.
• Stefan Koch (2/16) Jun 12 2018 write a static assert :)

consider this:

int f(int n) {
   m_n = n;
}

f(10); // ok
f(myTampleteFunction!(compileTimeParameter)); // ok
enum n = 10;
f(n); // I won't use this, but should also be ok
int x = 10;
f(x); // error
int g() { return 20; }
f(g); // error


How can I enforce that?
