Why do i need to import a freaking module to use int128?

[Kagamin]

That's tame, I have a module that defines
```
/// Signed integer of pointer size
alias ptrdiff_t intp;
/// Unsigned integer of pointer size
alias size_t uintp;
/// Signed integer of byte size
alias byte tiny;
/// Unsigned integer of byte size
alias ubyte utiny;
```
