Description

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.
