Leiningen will actually complain with this message if you try to make a project name that is too 'punny':
Sorry, names such as clojure or *jure are not allowed.
If you intend to use this name ironically, please set the
LEIN_IRONIC_JURE environment variable and try again.
Hah, that’s delightful! And a good lint rule besides. The Haskell world has a disproportionate number of packages whose names begin with H. Apparently my own joke wasn’t appreciated, though. :(
