sizeof(type)

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

May I use the wisdom of this list for a question that is not NetBSD-related?

Why does C's sizeof operator need parentheses when applied to a type?

A colleague argued that this resembles the typecast syntax (like typecasting 
nothing to the type in question).
I suspect some ambiguity without the parentheses, but I fail do make up one.
