Re: [RFC] Adding Python as a possible language and it's usage

Just another user here.

I'm not a fan of Python and I don't want it added as a dependency to my
favorite compiler. If I would build a minimal system with a toolchain, I
wouldn't want Python to be a mandatory component, so please don't. Thanks.

P.S. I don't mind Perl. It's a legacy tool next to Awk.
