That's true!

Sorry that I didn't much clarify the "pain" though:

It's quite like the experience of using parser combinator in Rust, where you could happily define the grammar and the parsing action using its existing utitlies. But once you have to do some easy wrapping, e.g. to make a combinator called `parenthesized` to surround an expression with parentheses, the "pain" kicks in, you have to leave as many trait bounds as possible since wiring the typing annotations become tedious. That came up while I was using framework like `winnow`.

Async Rust kinda shares some similar characteristics, utility functionalities might bring in many "typing wirings" that could terrify some people (well but I love it though).

That's probably fair.
