I want to create a reusable template for this purpose.

Why I can't use "staticMap" so that compiler it self would do this:

Just wrap some some symbol "args" with some expression at compile time.

It is the same as in C++:

D doesn't have expanding like C++

Unfortunately D has only simple automatic expading.

So how can one implement a reusable template "apply some function to each argument in template parameter pack" in D?

auto ToUnderlyingType(alias a)() {
    return cast(OriginalType!(typeof(a)))a;
}

void print(T...)(T args) {
    writeln(staticMap!(ToUnderlyingType, args));
}
