=head1 SYNOPSIS

See the grammar in file C<confusing.eyp> first.

This example illustrates how to solve the conflict using 
the postponed conflict resolution technique.

Compile the grammar with:

                 eyapp -TC confusingsolveddynamic.eyp

and execute it with:

                ./confusingsolveddynamic.pm -t -i -c 'x y c d'
                ./confusingsolveddynamic.pm -t -i -c 'x y c f'
