In languages/json/JSON/grammar.pg there's an XXX note starting
around line 29 that reads

    # XXX This should be called 'value', but...
    # RT#40069: [PGE] "value" can't be used as a rule name.
    
    token thing {
    ...

PGE no longer has difficulty with rules named 'value', so
someone can resolve the above XXX comment.
