What about making the redundant information the type/var itself instead

Yes, using "sizeof" and "typeof" on that first argument (for the malloc and then the final cast, respectively) sounds like a fine interface, and it's still obviously visually an assignment.
I think we already have some interfaces like this, I have no objections to that pattern.
