I haven't used perl 5.10 yet, but looking at the changes (available at <http://search.cpan.org/~rgarcia/perl-5.10.0/pod/perl5100delta.pod>), and in particular the section headed ``incompatible changes'', it looks like a small number of odd corners (for example, chdir FOO - unquoted argument now treated as filehandle not directory name) rather than a wholesale change like perl 5.8, which was binary-incompatible with earlier perls and therefore required any modules using the XS interface to C code to be recompiled. Perl 5.10 does introduce a couple of new operators (defined-or, spelt //, and smart-match, spelt ~~), and a number of enhancements which have to be switched on using the ``feature'' pragma - most of these changes have filtered back from the Perl 6 effort.
