[Python-Dev] Re: How about using modern C++ in development of CPython ?

[Abdur-Rahmaan Janhangeer]

I heard that rust has fewer target architectures. Is that a minus point
with regards
to C?

[Python-Dev] Re: Discussion about crash tolerance feature for gdbm module

[Dong-hee Na]

After discussion with Victor by using DM, I decided to provide
high-level API instead of low-level APIs.

- gdbm.open(filename, snapshots=(foo, bar))

will do everything at once.

Dong-hee
