  That's a pre 2.2 beta bug.

  BTW: Not in the upcoming 2.2 release, but soon afterwards we're
eliminating the prefix behavior of + and -.  There'll still be ADD and
SUBTRACT as prefix, but as some of you have experienced, having + and
- be both infix and prefix causes some ambiguity, and inconsistency
when you throw in - unary.  Just a heads up. :)
