Even with std.traits, you can't know which arguments are 
variadic. The only way to actually replicate a function is with 
string mixins and parsing the stringof of the function you want 
to replicate. This (ref int) thing does not help one bit and will 
only trick people into thinking they are properly replicating the 
call signature when they are not.
