"Writing L in L" is called metacircularity.

For as long as I've been thinking about writing a compiler, I've
considered metacircularity as an essential feature.  This was in 1995 or
so... The idea was already pretty common in the 80's.  That Perl people
begin to talk about it now is pure coincidence (or not).

I am interested in modular interpreters more than in adding translators
for other languages, but the former allows for the latter.

I doubt you'll be able to make, say, Ruby and Perl and Java people
agree on something about a common runtime environment.

BTW, I don't think "virtual machine" is an appropriate word to describe
anything in what I want to do.
