That's only true when the expression in question does not parse as unary
expression. Each of the following expressions is already a unary
expression, and would therefore not need parentheses if passed to sizeof:
a
1UL
"sizeof"
_Generic(a, int:5.0, double:5)
array[1]
printf("output")
mystruct.member
pmystruct->member
a++
a--
(struct tm){.tm_year=112, .tm_month=9, .tm_mday=18}
++a
--a
&a
*array
+a
-a
~a
!a
sizeof a
sizeof(int)
_Alignof(a)
