Iffys are a nice go-to in ts in general, because type inference is so handy and I'd rather not have a big pile of typed `let`s at the top that I have to assign

Iffys are a nice go-to in ts in general, because type inference is so handy and I'd rather not have a big pile of typed `let`s at the top that I have to assign into later. Even something as simple as a switch plays nicer if you iffy it and use it like an expression (similar to a match is rust)
