A few small tests later:

import std.typetuple;
import std.typecons;
import std.stdio;

void main() {
     int a, b;
     TypeTuple!(a, b) = tuple(4,5);
     assert(a == 4 && b == 5);
}

In other words, the language already has this.

Note that TypeTuple!(a,b) = TypeTuple!(b,a) also works, but sets both a  
and b equal to b.
