And it is, of course, called reverse Polish because nobody wants to remember how to say Jan Lucasiewicz. :-)

Does anyone know how the plans are coming in Perl 6 for having multiple front-ends for Perl, with the ability for different modules to be parsed and associated with the right one? I have heard that RPN is actually rather similar to Japanese. Of course we have the inflected lingua::Romana::Perligata (inflected languages include German, Russian, and according to co-worker several of the Indian languages), and of course the traditional positional Perl. Having them cooperate could be a very interesting experiment indeed. :-)
