+  const auto *A1 = &Arena.createSequence(symbol("A"), ruleFor("A"), {B});
----------------
I was confused by the forest here -- the fact that it doesn't reflect the grammar (I was trying to figure out why there is an ambiguous node for A by reading the grammar above)

I think there should be a comment clarifying the gap between the grammar and forest --  this is an artificial forest which is only for testing the dump purpose -- we only need the symbol bits from the grammar (I actual think `GLRTest::buildGrammar` is a better fit for the tests in this file).
