I already wrote about it in this thread ;)

More verbose:
Guile-3 changed the underscore `_' to a syntax keyword.
LilyPond (and others) currently use `_' as shortcut for `gettext'.
Guile-3 now proposes `G_' for gettext.

This change is unfortunate, imho: we need to change all occurrences of
`_' to `G_' ,likely `_i' as well...
