int operator ~(int x);  
uint operator ~(uint x);  
long operator ~(long x);  
ulong operator ~(ulong x);  
Paragraph 21 For each of these operators, the result of the operation is the bitwise complement of x. Paragraph 31 Every enumeration type E implicitly provides the following bitwise complement operator:
E operator ~(E x);  
Paragraph 41 The result of evaluating ~x, where x is an expression of an enumeration type E with an underlying type U, is exactly the same as evaluating (E)(~(U)x).
