It is not even necessary. I changed to keywords. The code uses: `(You see a ~obj on the floor.) And it is displayed as: You see a whiskey on the floor. You see a bucket on the floor.

Let change the rest also to keywords. > On Wed, Jul 9, 2014 at 9:28 AM, Cecil Westerhof <cldwester...@gmail.com> > wrote: > >> 2014-07-09 17:18 GMT+02:00 Thomas Heller <th.hel...@gmail.com>: >> >> Oh and its rare (outside of macros) to use symbols like that.
