Swift currently does not allow operators to use $ - I assume because the grammar reserves it in one place: `implicit-parameter-name`. I don't see why an entire class of identifiers has been eliminated, so I propose $ instead be reclassified as an `operator-character` so it can be used mixed in with other such characters, but prevents the introduction of `$Identifier`-style declarations that might conflict with implicit parameters.
