The only operators with precedence between & and && are ^ and |, though. In e.g. the expression from the sibling comment, `a & b == c`, writing & or && doesn't make any difference (aside from short-circuiting). I guess it's an issue if you write & instead of && in an expression that also involves a bitwise-OR (or | instead of || in an expression that also involves logical-AND), but that seems quite rare. I expect that reversing the precedence of the bitwise and logical operators would create problems a lot more often.
