I wonder if what we're missing are functions that operate on tuples and return 
tuples. We almost have them in the form of:

```
template tuple(A ...) { alias tuple = A; }
```

but the compiler wants A to only consist of symbols, types and expressions that 
can be computed at compile time. This is so the name mangling will work. But 
what if we don't bother doing name mangling for this kind of template?
