&gt;&gt;clearly Perl5&#x2F;6 has been an even bigger mess<p>The migration path from Perl 5 to 6 is like going from C to C++ or D. Basically there is no &#x27;migration path&#x27;. C didn&#x27;t go away after C++, neither did the whole rewrite C applications to C++,Perl 5 is not going to go way after Perl 6.<p>&gt;&gt; because they haven&#x27;t even managed to release the interpreter, much less start moving to it.<p>They released a beta and production release is coming out this christmas.<p>Clearly you have a lot catching up to do.
