=head1  SYNOPSIS

The grammar here generates the same language than the grammar 
in file C<nolr_k_grammar.eyp>:

  A : B C d | E C f ;
  B : x y ;
  E : x y ;
  C : /* empty */ | C c ;

This grammar confuses any LR(n) or LL(n) parser with a fixed amount of look-ahead.
The simplest solution is to rewrite the grammar as here
