Use a run-time Tuple instead of an AliasSeq:
import std.typecons;
auto args = tuple(0, 0);
static foreach (idx, val; args) {
static if (user_defined_function_exists_for_arg!idx) {
args[idx] = user_defined_function();

Now I want to extend it so that a caller can specify the values
of only some of the parameters. I tried using a static foreach
instead of the staticMap function. But I can't modify AliasSeq
values.
alias args = AliasSeq!(0, 0);

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

I have written a simple function that can call another function

auto rnd = Random(42);
auto rand_integral(T)() {

auto call_with_rand(alias fun)() {

Now I
