I'm not sure that we're taking about the same thing. Sometimes, to make
the grammar manageable, the lexer has to *dynamically* return 'typename'
instead of 'identifier'. Only semantic analysis can determine what is a
user-defined type (say 'foo'), so the lexer must be told at runtime that
'foo' is a 'typename' and not an 'identifier'.
See also the so-called lexical tie-in in the doc.
Thanks - that information is also in the old O'Reilly book, but I'm
afraid that it's not enough for this problem.
