Should be: sizeof(d) ?
"The sizeof operator yields the size (in bytes) of its operand, which
may be an expression or the parenthesized name of a type."
So the parentheses are only required for a type, not an expression.
sizeof(d) is the same as sizeof d which is the same as
sizeof(((((d))))).
Great! I'm learning something new still it seems :)
