You can in some contexts.  You can as the left-hand operand of a comma
operator, as the second or third operand of a ?: (when the other one is
also void, at least), and as the expression part of an
expression-plus-semicolon statement.  The first and third pieces of a
for-loop control are other such contexts.

Basically, the only thing you _can't_ do with an expression of type
void is actually use its value.
