I've just posted the latest version of Py (2.5e) to my home page, at:

    http://www.lanset.com/dcuny/py.htm

Features include:

 - calls using indexed variables fixed
 - dictionaries now use Jiri's hybrid lists
 - del with dot notation fixed
 - var ... syntax added
 - fixed bug in Ox, mishandling $pre directive

If you are curious about what Py can do, here's an example native support
for the 'dictionary' data structure (also called an "associated list"):

   s = {"name":"chester", _
        "color":"orange", _
        "proc":routine_id("length") }

The underscores are only needed if you are entering information from
interactive mode. This is the same as writing:

   s = {}
   s["name"] = "chester"
   s["color"] = "orange"
   s["proc"] = routine_id("length")

Which is exactly the same as:

   s = {}
   s.name = "chester"
   s.color = "orange"
   s.proc = routine_id("length")

Py allows calling variables as if they were routine names, expecting the
variable to contain a routine id value. For example, the two statements:

   ? s.proc("abcd")
   ? length("abcd")

are functionally the same. This allows Py to act like it's object oriented,
without having to introduce the notion of classes - an idea stolen from
JavaScript.

As usual, feedback is appreciated!
