__call__ considered harmful or indispensable?

[infidel]

I find it useful in certain situations.  In particular, I have used it
along with cx_Oracle to provide a python module that dynamically
mirrors a package of stored procedures in the database.  Basically I
had class StoredProcedure(object) and each instance of this class
represented a particular stored procedure in the database.  It just
made sense to use the __call__ method to make these instances
callable.  Seemed silly to use some other method to actually call the
stored procedure in the database from such an instance.
