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" ) ) {}
