Grammars 41-60.

Tests compiled manually in 2018 and 2019, re-packaged and extended (supplying test cases where needed) in 2022.

Note that some tests have alternate results for processors operating in non-standard modes, in particular modes in which they tolerate multiple definitions and undefined nonterminals or in which they do not tolerate non-productive nonterminals or unreachable nonterminals.

For a description of the form in which alternate results are recorded, see tests/misc-grammar/test-catalog.xml.

A simple toy grammar for a small set of English sentences.

Invisible XML Grammar

{ Sample grammar from Dick Grune and Ceriel J. H. Jacobs,
    Parsing techniques: A practical guide (New York: Ellis Horwood, 1990;
    Second edition New York:  Springer, 2008), pp. 34 (1e) and 26 (2e).

    Rules for ws added for convenience; Grune and Jacobs assume the lexer
    eats whitespace. Peculiarity:  whitespace is allowed but not required,
    and it is allowed after any word but not at the beginning of the input.
