Research direction
Reproduce the diagnostic in Positron with the {future} package, library(future), a configured plan, and the %<-% assignment construct. Trace the diagnostics entry point that reports the missing symbol and compare behavior before and after the package setup; done means the valid construct no longer produces a missing-symbol diagnostic.
