Description
I complain about R's nonstandard evaluation a lot because it's hard to inspect objects outside of their scope.
But I'm doing the same thing in DataFramesMeta with @passmissing, @byrow, and soon @astable. I should write @passmissing, @byrow, etc. so that they produce either a pair or a collection of pairs that someone can inspect.
This is motivated by discussions on discourse and this issue in DataFrames.jl.

Research direction
Start with the implementations of @passmissing, @byrow, and @astable, then read the linked DataFrames.jl issue and the referenced discussions for the intended inspectable representation. Confirm whether each macro should produce a pair or a collection of pairs, and define tests for behavior outside DataFramesMeta macros. Done means the macro flags expose an agreed inspectable representation.
