I know it's bad form to reply to my own question, but I think I
found a reasonably simple way:
```d
string prnType(Vec3 vec){
return vec.match!( t => typeof(t).stringof);
}
```
which is hardly worth making into a function of it's own. Other
suggestions are welcome of course.
SumTypes are really tripping me up. Unlearning years of writing
C takes more time then I'd prefer.
