Does the benefit of fixing the Guix API used via a user profile
installed Guix package outweigh the cons of downgrading the version of
guix used as the user's package manager?  I don't think so.  By
installing the inner 'guix' into your user profile, you are basically
downgrading its version compared to the one you used to install it.
That's a pretty confusing thing to happen for most users.

As paren suggested, I think it's best to enter a dedicated 'guix shell'
profile with Guix when developing with the Guix API, else use the 'guix
repl' ability to run scripts.

It may be slightly inconvenient, but it's better than allowing Guix to
be silently downgraded upon unsuspecting users, in my opinion.
