That's not a downside: it's at least a wash.

In C++ you manage memory and the language manages resources. In
Python you manage resources and the language manages memory.

RAII is merely one way of minimizing complexity. Garbage collection
is another way.

If you've already got a generic, language-supported way to manage
resources (like RAII with deterministic destruction), then why bother
with garbage collection?

Because now you have to manage memory? Did you read my post? You
have to manage one thing or the other.


I'm not trying to knock it; it was a big step
up from C-style "who forgot to delete a pointer" games. It just seems
to me like a solution to something that's no longer a problem, at least
in well-written C++ code. I'll take destructors over GC any day.

About 2% of the objects I creat have resources other than memory. I
would rather manage resources of 2% of objects than manage memory of
100%. YMMV, but I suspect mine is the more common opinion, if the
recent (like, 10-year) trend in programming languages is any
indication.
