Can any of those execute or interpret some code and then compile the
results of that into a non-interpreted executable?  That's what I had
desired, if it wasn't clear before.  Otherwise, you're still doing the
special computations at run time, only slower.

Maybe I HAVE heard of some interpreters (Python?) saving an excecutable
image of themselves after running a while.  Is that what you're thinking
of?  Will all of those language systems above do that?  It's not quite
what I was thinking of, but I guess it meets my (poor) specifications.
