The & operator can function as either a unary or a binary operator.

The unary & operator returns the address of its operand (requires unsafe context).

Binary & operators are predefined for the integral types and bool. For integral types, & computes the logical bitwise AND of its operands.
For bool operands, & computes the logical AND of its operands; that is, the result is true if and only if both its operands are true.
