When I wrote a lot of Swift code, I noticed I can't search quickly for the places where I just ! to not care yet, to replace those with ? later, the ! symbol is used in strings ("Hello, World!", for example), compares (!=) and bool inverses (!bool), so I couldn't just search for the ! character to find all the infallible unwraps I wanted to change without going through a lot of != and !bool.

I think that's what happened with Kotlin too, where they use !! for infallible unwraps.

What do you think? :) Cool language you have here, I will definitely try it out! Thanks.
