Summary: Multiple variadic template argument trick broken in
2.068.0-b2

There is a trick that allows multiple variadic template arguments in a function
if the second variadic template argument list is derived only from the function
arguments. This trick worked in versions prior to the 2.068.0 betas, but it
does not work with them. Exmaple code:
---
import std.stdio : writeln;
template alpha(alias Beta, Charlie...)
{
void alpha(Delta...)() if (Delta.length == 0)
{
writeln("First");
}
void alpha(Delta...)(Delta delta) if (Delta.length > 0)
{
writeln("Second");
}
}
void main(string[] args)
{
int a;
alpha!(a)();
}
