I don't know enough Ruby to sensibly comment on this but PMCs determine how your basic data types behave. Let's take an easy example: the "add" method. If you get a Perl scalar with the value of "12ab" and another with the value 1, and you call the "add" vtable method on the two, it's that method's responsibility to produce the answer, a PMC with the value 13. In Python, however, you'd want to raise an "illegal argument type" exception. I don't know what you'd do in Ruby, but Parrot_rubystring_add would be the right place to do it. :) -- "I'd crawl over an acre of 'Visual This++' and 'Integrated Development That' to get to gcc, Emacs, and gdb.
