I found `auto` and `ref`(yes just `ref`) return types very useful 
for bypassing the type system, eg.:
```D
///function requires lvalue and the return value can be of any 
type while still being the same data.
ref mutateSomething(A)(ref A something) {
     static if (isArray!A){/*...*/} else {/*...*/}
     return something;
}
```

Other than that, i've found tuples limited in usage compared to 
just using a struct or static arrays.(the main problem is the 
inability to use runtime indexing even if the types match.)

The rest, i don't use from lack of interest or awareness it even 
exists.
