Topic: `pass_to`-like `dbg`

Sorry if this has been suggested already, but in the static dispatch world, I'd love for dbg to support a syntax similar to pass_to:

artists
    .dbg()
    .filter(.is_starred.dbg())
    .dbg()

It'd be so easy to drop that anywhere, no need to fiddle with parens or rearrange things like you might have to do in Rust.

This definitely makes sense if we have .pass_to, otherwise this is the only place in Roc where we have a reserved method. I'm here for it though, it's extremely natural

this makes sense to me!

you already can't name a field dbg anyway because it's a reserved keyword
