There are differences in the details. JS with is much less powerful than implicit arguments or effect systems. The basic concept is similar; all deal with dynamic scoping in some way.

Effect systems can change control flow (that's the point of many effects, such as exceptions) so they require capturing continuations.

Implicit arguments usually have compile-time search / composition.

Rye contexts seems like they have neither of the above, but I've only skimmed through the description.
