[PY!] Playing with Py

Hope this is not considered off-topic, but Dave's Py turns out to have some
very interesting and potentially userful features. Here's one:

----------
-- fruit.pi  --
----------
variety = ""
color = ""
price = 6.99

def info()
  printf(1,"Fruit is %s, color is %s, and price is %4.2f\n",
                variety,color,price)
end def

Save the above as "fruit.pi", then run Py in interactive mode:
+==========================================+
| Py version 2.2a                          |
| Built: October 20, 2000                  |
|==========================================|

| Euphoria (c) Rapid Development Software  |
| Dictionary code (c) Jiri Babor           |
+==========================================+

type 'bye' to exit

Py > import "fruit.pi" as Apple

 Py > import "fruit.pi" as Peach

 Py > import "fruit.pi" as Cherry

 Py > Apple.variety = "Mackintosh"

 Py > Cherry.variety = "Moreton"

 Py > Apple.color = "Red"

 Py > Cherry.color = Apple.color

 Py > Apple.price = 3.99

 Py > Apple.info()
 Fruit is Mackintosh, color is Red, and price is 3.99

Py > Cherry.info()
 Fruit is Moreton, color is Red, and price is 6.99

Py > Peach.info()
 Fruit is , color is , and price is 6.99

Py >bye

It turns out that Py can import the same file numerous times, and each time
creates a completely separate and independent set of variables and functions
within the namespace given. Here are my long-awaited structures, plus quite
likely some interesting OOP-like characteristics.

Hmmmm.
