Hi! Who has used the optparse-applicative package successfully? I'm having trouble with getting it working even with a simple flag. At first I thought there is an issue with a Stack interpreter because I wrote my program as a Haskell script, but when I rewrote it as a full-blown Stack project, the problem was the same. I have a single flag with the short `-g` option and when the program is invoked with it, it's not recognized: ``` $ stack run -- -g optparse-test-exe: unrecognized option `-g' Try `optparse-test-exe --help' for more information. ```
