]- I think that we should have this possibility.... Of course if something
can be solved w/o backtracking it will be solved in that way ..... perl
parser will not parse only PERL but also many other TARGET-languages .....
and one more feature will not be worse but better (backtracking, score based
decision, lookbehind etc... )
