Ah, the way "property_path" is defined via "symbol_list_rev" and symbol
lists also in function arguments are defined as being able to contain
either '.' or ',' means that even if one forces the first separator to
be a '.', the following separators are hard to avoid being also
permissable as ','.
So navigating around that inconsistency is pretty ugly: it will
sometimes work and sometimes not. But maybe definition and call of
those kind of separated variables should at least be identical and
consequently require a first dot even if for technical reasons the
following separators may happen to admit commata.
