Optional args

[zahanm]

DEFINE rank_k_teachers FOR shell ON me, teachers USING k = 5 DO
  PERFORM "python ranking.py"
  RETURN teachers_list
END

Throws an error at compile time. Not urgent.

For the time being, a simple workaround is to just leave off the "USING" clause. You can still pass in optionals args when calling the function:

COMPUTE rank_k_teacher ON me, users USING k = 10

Optional arguments are no longer supported in Dog. Not to mention that this is an old issue that we never quite got around to addressing. Closing...
