Haven’t learned Rust yet. I see they debated this:

   let and let mut
   let and var

And went with the verbose option.

Swift went with the succinct option, which I love about the language. In practice I suppose I do mostly type “let” in Swift so it doesn’t matter much

Swift, however, chose ‘func’ instead of ‘fn’, after much debate.

Those little things that are debated initially, then forever
