In complex cases for sure—I did a little parser thing once and didn’t use do_ at all, but I honestly don’t write a lot of recursive functions. I mostly do simple cases and (and I’m entering into mega bikeshed territory here) I hate when things have names for the sake of having names… if that makes sense? Like when I see _other -> true in a catch-all or the like. I name my _ vars 99% of the time but case like that I’m like, “Duh, I know it’s ‘other’!”
I dunno, I’m procrastinating on a project right now
