rust-cpython: add panicking version of borrow_mut() and use it The original borrow_mut() is renamed to try_borrow_mut(). Since leak_immutable() no longer incref the borrow count, the caller should know if the underlying value is borrowed or not. No Python world is involved. That's why we can simply use the panicking borrow_mut().

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
