  1. operator cleanup

    authored
    The (ivars) and (ivar-accessor) operators now do nothing and should
    be removed. Instance variables are now implicitly created and
    stored using associated objects, so there is no overhead for their
    potential use.
    
    The (cmethod) and (imethod) operators are still available but with
    a deprecation warning in the log. They should be replaced by (+) and
    (-), which are more consistent with Objective-C usage.
    
    The (def) operator is gone. It was carried over from Ruby and in
    practice, the equivalent (function) is preferred.

  1. comparison operators now use compare:

    authored
    The <, >, <=, and >= operators now all rely on the
    compare: method to perform the necessary tests.
    They also now accept an arbitrary number of
    arguments (at least one!).  Each operator returns
    t (true) if its arguments are ordered appropriately
    and nil (false) if not.  For example,
      (< 1 2 3) returns t, and
      (< 1 2 2) returns nil
    
    This allows us to write functions like this one
    which tests that its argument is a list of objects
    sorted in increasing order:
    
    (function increasing (mylist)
         (eval (cons '< mylist)))
Something went wrong with that request. Please try again.
