I have a function void foo(...) and a function void bar(...) and I want to call bar from foo, in a way that bar receives the same variable argument list than foo.
Is that possible in D?
Thanks!

Explanation: Every actual argument list must be known at compile time.
The va_list may be passed as an argument to another function, but calling va_arg() within that function causes the va_list to have an indeterminate value in the calling function. As a result, attempting to read variable arguments without reinitializing the va_list can have unexpected behavior.
The C standard mandates that the only place the identifier __VA_ARGS__ can appear is in the replacement list of a variadic macro. It may not be used as a macro name, macro argument name, or within a different type of macro. It may also be forbidden in open text; the standard is ambiguous.
if you use templates yes
void foo(A...)(A a){
bar(a);
}
void bar(B...)(B b){
//...
}
the a gets expanded that compile time to what arguments it was called with
you can also slice[] off some arguments, or you add an argument to the list

I think core.vararg might be of use.
