I agree it can be improved, but I'd also have to read the code to know
what each level exactly do.

I think it could make things simpler to use nouns for the level, as they
could mean something without having to be explained to verbosely, e.g.:

debug (very verbose)
info (include some extra messages)
warning (warnings and errors -- the default level)
error (errors only)

Basically like what the levels of the 'logging' Python library are
expected to do, which the logging library included with guile-lib is
inspired by.
