    An LR(k'') grammar is clearly unambiguous''', since the definition
    implies every derivation tree must have the same handle, and by induc-
    tion there is only one possible tree. It is interesting to point out further-
    more that nearly every grammar which is known to be '''unambiguous     is
    either an LR(''k'') grammar, or (dually) is a right-to-left translatable
    grammar, or is some grammar which is translated using "both ends to-
    ward the middle." Thus, the LR(''k     ) condition may be regarded as the most
    powerful general test for nonambiguity that is now available.
