 Here's how files on the watchlist are handled. If one of the files on the watchlist changes, the cache is invalidated (just as it would be if @racket["pollen.rkt"] changed). If the cache can't find a certain file on the watchlist, no error will arise. The file will simply be ignored. Therefore, to avoid unexpected behavior, the best policy is to use complete paths (or path strings). One way to generate a complete path to a local file is with @racket[define-runtime-path]. Another way, if you're using a module that's already installed as part of a package, is with @racket[resolve-module-path]:

-Here's how environment variables on the watchlist are handled. By default, the cache always watches the default @racket[#"POLLEN"] environment variable, but no others. By listing other environment variables in the watchlist, Pollen will watch those too. Unlike files, environment variables don't change during a session. But separate caches will be maintained for each distinct value of an environment variable.
