Well, it's a change, a semantic change. It's almost certainly going to
break _something_.

Hi Ian,
I apologize for trying your patience with the badly written code
example. All objects were meant to be ThirdParty(), the demo was only
to show how a slice() filter could have been applied for the reasons
PEP357 made index() to exist.
eg: because numpy items passed to __getitems__ via

As above, you're looking at the compiler code, which is why you're

Hi Ian,
There are several interesting/thoughtful things you have written.
I like the way you consider a problem before knee jerk answering.
The copying you mention (or realloc) doesn't re-copy the objects on the
list.
It merely re-copies the pointer list to those objects. So lets see what
