@9rnsr: This brings something to light, we can't introduce multiple aliases to the same type with the new alias syntax, IOW:

```D
alias int* int_ptr, intPtr;   // ok
alias int_ptr, intPtr = int*; // NG
```

I'm not sure whether it /should/ be supported though. It looks a little akward because of the assign expression `=`, so maybe it should stay unsupported.
