- The operand of sizeof can be a unary expression or a parenthesized type name, with expressions not requiring parentheses.
- Parsing sizeof involves first checking for an opening parenthesis and attempting to parse a type name; if that fails, treat it as an expression.
- Compound literals like sizeof(int){0} complicate parsing because they may include postfix operators after the closing brace.
- One solution is to handle compound literals by checking for a '{' token after a type name and then parsing any following postfix operators.
