I don't know that shift/reduce conflicts qualify as a "problem."  They're
an ambiguity in the grammar, but yacc (and presumably lojban) generates an
unambiguous parse in these cases by resolving in favor of shifting instead
of reducing (I think).  So I don't know if this is something that needs to
be "fixed," more just understood.

Or am I missing something?
