[Pharo-users] can I do something like this with Double Dispatch

[Roelof Wobben]

Hello,

Just thinking how to solve the bowling challenge from exercism.
but I wonder if I can do something like this in the method that checks 
if I have the right object

I was thinking about this :

Result
-- Strike
-- Spare
-- allOther

then In  Strike something like this

checkForBonus: number1 score2: number2
  ^ number1 + number2 == 10

or am I thinking the totally wrong way to solve this?
