So I propose the following new feature:

1) A scripting language is put inside git. Perhaps a version of python
or ruby or go or ... (no need for a 'new' language)

That sounds nice but ...

2) If a project contains a folder called .githooks in the root of the
code base then the rules/scripts that are present there are executed
ONLY on the system doing the actual commit. These scripts are run in
such a limited way that they can only read the files in the
repository, they cannot do any networking/write to disk/etc and they
can only do a limited set op actions against the current operation at
hand (i.e. do checks, parse messages, etc).

... how would you prevent Ruby/Python/Go/$GeneralProgLang from
executing arbitrary code?

Some kind of sandbox?

Like I said, this is just a proposal and I would like to know what you
guys think.

I love the idea but I'm not sure how feasible it is. I think you would
be forced to copy an existing language and somehow "make it secure"
(seems like a maintenance nightmare) or to create your own language
(potentially a lot of work). But perhaps something more declarative
might be usable?

As far as I'm concerned it should be the 'best suitable' language for
the task at hand.
