Look at my last example posted a few minutes before this.

You'd say the C needed typedefs.

But in the original language, type declarations are clear enough that 
they don't need typedefs.

The typedefs help to mitigate a problem in one language that doesn't 
exist in the other. Surely it's better to have neither the cryptic type 
nor the typedef. Everything would be much cleaner.
