I got the impression that this is about embedding the parser code into a
C++ class so that the names becomes local to the class. What Philippe
Bekaert suggests would then be the first step.

-- But one still has to give thought how to make those macro names that the
parser uses local.

-- Another problem is how to deliver the parsed value in a pure (local)
fashion. Currently one has to write something like


my_type global_value; // Global variable



sentence: foo { global_value = $1; /* Deliver the global value */ }

This is not good if one wants to write thread-safe parsers. -- Somehow, one
must be able to ensure that every invokation of the parser only uses its
own local values.
