Perhaps this is a solution in search of a problem but I recently
encountered this situation in one of my projects.
I have an object, foo, which, due to the references it contains, I'd rather
not keep around longer than necessary.
I use foo to instantiate another object:
bar = Bar(foo)
bar is free to manipulate foo however it wants and even del it if
necessary. However, since the foo name is still around, those resources
won't get cleaned up even if bar is done with them. The simple solution is
bar = Bar(foo)
del foo
bar.do_stuff()
I think it would be a nice (and, I hope, painless) addition to the Python
grammar to have del return a reference to the underlying object. That way,
I could simply do
bar = Bar(del foo)
What do y'all think? Juice not worth the squeeze?
