Very efficient built-in univariate and multivariate random number
generation would be a nice touch ;-)!

If you could manage this you would definitely get peoples attention.
Most modern array/matrix interpreted languages: Matlab, S-plus, R, Octave,
Euler, IDL, Yorick, Ox, GAUSS etc., etc., etc. have most of your other
points covered. However, all of them suffer from the fact that they are
too slow for intensive simulation. I personally use a couple of these
regularly and when the going gets tough re-code sections that are slowing
things up in Fortran95 for dyn.loading. However writing some code in your
favorite matrix language, adding some type declarations and compiling the
sucker to a fast binary would be a nice touch. The only in-development
project trying for something along these lines is LUSH:
http://lush.sourceforge.net/
Unfortunately they are using the dreaded lisp infix syntax.... urrrggh I
can't stand that ;-)! I suppose I'll just stick with my Python, R,
Matlab, and Fortran95 mix until you are finished your project ;-).
Cheers,
Jason

If you follow the link to the 920 programming languages on page
http://wombat.doc.ic.ac.uk/foldoc/contents/language.html
you will see that at least 5 languages are missing:
A, A+, J, K, Q-Nial
