The above code asserts. Is there some other way to compare mixed tuples,  
or should i roll my own comparison function?

Look for this problem in the digitalmars.D.learn group, because I have seen
this problem recently solved here (I don't remember the solution, it was easy).

Yeah. is( T == U ) only works for type tuples, though. Had to write my
own comparison code. I'd recommend something like this be added to Phobos.

template SameTuple( T... ) {
     template As( U... ) {
         static if ( T.length != U.length ) {
             enum As = false;
         } else static if ( T.length == 0 ) {
             enum As = true;
         } else static if ( T.length == 1 ) {
             enum As = is( T[0] == U[0] ) || T[0] == U[0];
         } else {
             enum As = SameTuple!( T[1..$] ).As!( U[1..$] ) && is( T[0] ==  
U[0] ) || T[0] == U[0];
         }
     }
}

Usage:

if ( SameTuple!( int, "a" ).As( int, "a" ) ) {}

Looks nice. There are many small bits of functionality like that that are
missing still in Phobos and can be added. I suggest you to put that code in a
bugzilla entry (otherwise I can do it myself) with a good unittest{} and if you
want a ddoc comment too.
