Hi Nicklas, I enjoyed some of your articles. However, I'm having trouble wrapping my mind around this one. I have a mathematically oriented program I'm writing. When I do a search for the word "if" I get around 2150 results. Are you suggesting that, instead of writing if-else, I should have taken the time to think of class structures to replace the 1+ cases the if else's address? Making for thousands of custom classes?
