Hello Ludovic,
Apologies for a long reply.

I think the patch is no longer needed, because ‘pypi->guix-package’
returns false (‘#f’) and REPL survives if a package doesn't exist:
--8<---------------cut here---------------start------------->8---
scheme@(guix import pypi)> (pypi->guix-package "psutil")

$3 = (package (name "python-psutil") #; more fields here)
scheme@(guix import pypi)> (pypi->guix-package "psutils") ; ‘psutils’ doesn't
exist in ‘pypi’
$4 = #f

WDYT?

Thank you! Based on this I wrote a macro:
(define-macro (try function)
`(catch 'quit (lambda () ,function) (const #f)))
but I don't know how to make it available after invoking ‘guile’ in
Bash. Putting the macro in ‘~/.guile’ doesn't help unfortunately.
Thanks,
Oleg.
