I found a few people who had tried something before, and I also found some references to it in a few places around abilites. After reading up on abilites it seems like the right thing to do. I saw some mentions on Arithmetic abilites but not enough to find a solution to my problem.
I want to use arithmetic operations on my opaque types (+, -, /, *). Is there a way to achieve this?

Luke Boswell (Feb 18 2024 at 21:05):I think the TLDR is there is no way to customise infix operators. You can implement Eq ability to use ==
Jonas Schell (Feb 18 2024 at 22:00):Thanks Luke, I'm totally fine with not having them. I just wanted to make sure I hadn't missed anything.
