	Here I am!

	Do you mean to create an extension to a traditional language?  I guess
it can be useful, but traditionally one would implement a embeddable
(sub)language, like SQL is or Tutorial D aims to do.  AFAIR, D4 is also
meant to be embedded.

	The trouble is, each language will have its own syntax, and it will be
somewhat of a pain to learn one extension to each language and another
for interactive usage.  I would favor using Tutorial D or D4 embedded
everywhere except at functional languages, that are clearly different
enough, and interesting enough, to warrant a tighter integration.

	At the moment all bets are off, so you could have a winner.

	Ideally Duro or something the like would become that engine.  Given
that something in Duro already exists, have you considered making your
library a Python interface to Duro?

	Point is, I guess at this moment we win more by collaborating than by
competing.

	Do you want to host it at tutoriald.sf.net?

	If so, I could transfer administration, or include you... I have to
look for a job, so no time to do it myself.
