New issue 57 by paulhaeb...@gmail.com: Is __del__ supported? Is garbage
collection working?
http://code.google.com/p/tinypy/issues/detail?id=57

tinypy is amazing. Very nice to see such a concise implementation
of python!

What steps will reproduce the problem?

1. try to run this code:

ndel = 0

class rect:
def __init__(self, orgx, orgy, sizex, sizey):
self.orgx = orgx
self.orgy = orgy
self.sizex = sizex
self.sizey = sizey
self.list = [];
for i in range(10):
self.list.append(i)

def __del__(self):
print("del")
ndel = ndel + 1

for i in range(1000):
a = rect(0,0,100,100)
b = rect(0,0,100,100)
b = a

print("__del__ called " + str(ndel) + " times")
print("bye")

What is the expected output? What do you see instead?

I was expecting __del__ to be called like in cpython. Is garbage collection
working? I added printf to gc.c and it shows these functions being called,
but the __del__ function is not being called.

After adding some printfs it looks like garbabge collection is happening
fine, the problem is that __del__ is not being called. Maybe if I study
the source I can make it work...
