( To change the subject slightly: )
Craig Chambers also wrote a paper on "Predicate Classes" -- an
instance for which a given set of predicates is TRUE is defined
to be a member of that Predicate Class -- which recalls an old
Python thread I started once about declaring things to be 'Numeric'
or a 'Sequence' as a shorthand for stating that not only does the
class support all of the required methods, but it also supports
them with a reasonable semantics.
( And I know I've mentioned before that I would like to try
to figure out how to add Self-like method specializations and
optimizations to Python. )
There's probably a few other good ideas to be mined from Chambers'
BTW: Thanks, Mark, for directing the discussion AWAY from
whitespace/block-delimiters syntax to something more interesting! ;-)
