Livagian, my engelang, uses polish (i.e. head-first), and also allows no unmarked variation in the number and ordering of a word's dependents. The result is that it can be unambiguously parsed incrementally with no lookahead and no backtracking. Flexibility of constituent order is achieved by having devices that explicitly mark reorderings and changes to the number of a word's dependents. --And.
