I like TIScheme quite a bit.   As long as you have the memory, it's pretty
thorough.  Scheme has some variations from lisp, such as treating functions
just the same as any other data object in terms of referencing/dereferencing,
passing them around; it also emaphasizes block structuring and scoping
much more than I find in lisp.  You can manipulate the environments as
data objects, if you really want to, for example.

Example:  I wrote a simulation of a (very _tiny_) computer in Scheme, starting
at the flipflop level, that could run a program.  Only 4 address bits, so
it had only 16 words of 4-bit memory, but making it bigger would have just
been a bit more tedious (it was bit-sliced).

disclaimer:  a number of people (not including me) worked with or at TI on
the package's development.  On the other hand, I'm not much of a lisp hacker.
