I hadn't realized that Sapphire was ever thought of as anything beyond
a one week proof of concept and code reuse.  It was a good demonstration
of what is possible in that time.  It is sad that the wheels you are
reusing were not flexible enough to be used on the full range of what
Perl supports, but there are many other open source projects which
would find where you got very acceptable.

I haven't been following the development of Perl 6.  I do know it is
being built on Parrot, which is intended to be a good platform for
building scripting languages.  However I think it would be very nice if
Parrot contained reusable libraries that others can use.  Perl 5 had
lots of useful stuff in it that others liked, but it was virtually
impossible for other projects to identify and borrow any smaller
useful chunk than an embedded Perl interpreter.  (OK, mini-Perl
interpreter.)  Which is why, for instance, even though everyone and
their dog advertises Perl-compatible regular expressions, only Perl
uses Perl's RE engine.

I could easily understand if that wasn't going to be feasible, but if
it was then it would be a good thing if the Parrot project began
advertising the availability of highly portable libraries for general
use long before the rest of Parrot (let alone Perl 6) was delivered.
