How about statically compiling the code? Then you do not need to distribute
the runtime library. It should not make a big difference for the rather

As an exercise in using the new set C API, I've replaced the
"interned" dictionary in stringobject.c with a set. Surprisingly,
what I thought would be a simple exercise, took several hours to
implement and debug. Two problems are worth mentioning:

Thanks for the good word. I've reworked the code a little bit and
fixed the comments. I don't have svn write access, so someone else
I would like to share a couple of observations that I made as I
studied the latest setobject implementation.
1. Is there a reason not to have PySet_CheckExact, given that
PyFrozenSet_CheckExact exists? Similarly, why PyAnySet_Check, but no
PySet_Check or PyFrozenSet_Check?
2. Type of severa
When an extension type Foo defines tp_getattr, but leaves tp_setattr
NULL, an attempt to set an attribute bar results in an AttributeError
with the message "'Foo' object has no attribute 'bar'". This message
is misleading because the object may have the attribute 'bar' as
implemented in tp_getattr

Setobject code allocates several internal objects on the heap that are
cleaned up by the PySet_Fini function. This is a fine design choice,
but it often makes debugging applications with embedded python more
difficult.
I propose to eliminate the need for PySet_Fini as follows:
