As usual, it is a bad idea to include ‘.’ in the search path, because it
makes it easy to unwillingly execute untrusted code.

More generally, ‘GUILE_LOAD_PATH’ is a user environment variable (like
$PATH, $CPATH, etc.), so it’s up to the user, not to Guix, to set it up
correctly.

So I’m closing this bug, but of course, I remain open to discussions on
improving Guix to better support “overlays”.

Thanks!
