You cannot. meta-programming and compile-time evaluation are

Sorry, I wasn't clear. The code I wrote does not actually
_produce_ the random values at compile time. It is just a
template that evaluates to a function call where each argument is
given as `gen_rand_integral()`. So if I call
call_with_rand!(add)();
It will expand to
add(gen_rand_integral!(int)(), gen_rand_integral!(int)());
But I want a way to expand this to
add(gen_rand_integral!(int)(), user_defined_generator!(int)());
