We're always open to suggestions!

The idea of an increment operator (like C's ++) has
come up before.  But we're rather hesitant to add that
to the language because of the problem of side effects,
not to mention the ambiguity in an expression like
"a+++b".  (ie., is it "a+(+(+b))" or "(a++)+b"?)

However, we do like the idea of adding assignment
operators +=, -=, etc.  (Like in C or Perl).  So you
could code stuff like:

      eval x += 1                    -- increment by one
      eval arr(proc('abc')+14) -= x  -- decrement by x

Anyways, I'm sure you'll find this on our next RPG
"enhancement poll".

Cheers!  Hans
