[Sharing]Tuple to variables (My Function)

Hi,
Sooner I asked about this ([Doubt] Variadic arguments as
reference (Possible?) - -
http://forum.dlang.org/thread/jwujjhjizkovvmbegaio@forum.dlang.org).
In fact my intend was to recreate a feature that I like in
Python, where you can assign variables from a tuple, e.g.:
pos = (10, 20)
x,y = Pos
or
RGB = (255,255,255)
r,g,b = RGB
Thanks to the fellows who help me early morning, I wrote the
workable version below:
import std.stdio;
import std.typecons;
import std.variant;
void tupleToVar(A, T...)(A inTuple, ref T listParams){
foreach(i, ref p; listParams){
if(!(i<inTuple.length))
break;
p = inTuple[i];
}
}
void main()
{
auto myTuple = tuple(1,2,3,"Test");
Variant a, b, c, d;
tupleToVar(myTuple, a, b, c, d);
writeln(a);
writeln(b);
writeln(c);
writeln(d);
}

It would be nice if it could appear more like python, but I think
this would be a internal dev.
