I like clap a lot, however I find that clap derive is not very easily discoverable. I always have to google for the right macro incantation to get what I want. Whereas editor completions from rust analyzer get me quite far without needing to leave my editor when I'm just using an ordinary library.

I think this is more a criticism of rust-analyzer than clap itself, any macro-heavy library I have similar issues with.

(Yes I know clap can be used without derive, but I'm willing to deal with the pain to parse directly into a struct)
