unless delete is explicitly called, I don't believe the 
destructor would ever be called, it would still have a reference 
in the static foo_list object that would stop it from being 
collected by the gc.

I could see the constructor situation being a problem in threaded 
code as well, tho it may be bad practice, I don't believe the 
insert(this) would actually break anything.

The scope(success) is a good idea either way however.
