Otherwise we always get multiples of:
imported module (lily) overrides core binding `_'

This is due to:
** Define top-level bindings for aux syntax: `else', `=>', `...', `_'

These auxiliary syntax definitions are specified to be defined in the
R6RS and the R7RS.  They were previously unbound, even in the R6RS
modules.  This change is not anticipated to cause any incompatibility
with existing Guile code, and improves things for R6RS and R7RS users.

** Conventional gettext alias is now `G_'

Related to the last point, since the "Fix literal matching for
module-bound literals" change in the 2.2 series, it was no longer
possible to use the conventional `_' binding as an alias for `gettext',
because a local `_' definition would prevent `_' from being recognized
as auxiliary syntax for `match', `syntax-rules', and similar.  The new
recommended conventional alias for `gettext' is `G_'.
from the release announcement for guile-2.9.6`_' 06.html

Could we silence the warnings?
If so, then we cannot use guile's own`_'. A loss or not? Not sure...
