Feedback on future function and flag renames

[AndydeCleyre]

Hello!

I plan to rename some things eventually, and would appreciate any feedback and suggestions about new names for existing actions.

First up: [--py pypy|current]

This is available to a handful of functions, but especially envin and activate. It used to have a dedicated python2 option. Now it doesn't seem justified to have a special pypy flag when the --py current behavior can be used to achieve it, using an external python runtime switcher, like mise, asdf, or pyenv. So --py current can become a single flag with no arguments, I just need to name it.

Right now the help looks like:

--py    -- Use another interpreter and named venv

And will become something like:

--this-python    -- Use the python from your shell's PATH, and a venv named for its version

Some ideas:

• --this-python
• --path-python
• --current-python
• --current

Second: pypc

Current help:

# Inject loose requirements.in dependencies into a PEP 621 pyproject.toml.
# Run either from the folder housing pyproject.toml, or one below.
# To categorize, name files <category>-requirements.in.
pypc [-y]

Third: open to more suggested renamings
