a op1 b op2 c
Also, it seems each operator will have to have a associativity to handle a future operator for exponentiation or (also potential future) custom operators.
Finally, the “What you need to know” section doesn’t mention orelse. Where does that fit in?
The point is that there is no longer a global ‘precedence number’ where the operator with the higher precedence binds tighter. Instead, it is only valid to write your example for some combinations of op1 and op2; other combinations will require explicit parentheses.
Presumably orelse is not in the table because it requires parentheses for any other operator.
