Description

As referenced on discourse, lots of users have trouble with complicated source => fun => dest pairs. Maybe something like R's across might be useful.

It could live here. It could also live in a 3rd package that we re-export, like Chain.jl.

Research direction

Start with the issue's referenced Discourse discussion and compare R's across API with the possible Chain.jl approach. No repository file or test is named, so first establish the intended API and whether it belongs here or in a re-exported package. Done means the project has an agreed design for handling multiple columns and an implementation with corresponding coverage.
