Operators
• Infix notation x op y is x.op(y), postfix notation x op is x.op()
• Only + - ! ~ can be prefix—define method unary_op
• Assignment xop=y is x = xop y unless defined separately
• Precedence depends on first character, except for assignments
• Right associative if last character is a colon :
• x(i) = x(j) is x.update(i, x.apply(j))
• There is no ++ or -- for numbers. Use x += 1; y -= 1
• Use x == y to compare objects—it calls equals
