It strikes me that Scheme is largely an academic language. Granted, there are
a few Scheme devotees out there who worship the language, but they seem to be
all at MIT or Rice. I think they've even written modules for web programming
with Scheme, but I have to wonder what psychotropic drugs they were on when
they did it. Scheme, like most functional languages, is based on functions.
One doesn't store values in variables, you have a function that returns the
value, which is then piped into another function, etc. I have to say I learned
recursion really well from it (as there are no iterative constructs, all
looping is done via recursion), but I wouldn't want to use it in daily life. I
don't think it's appropriate for the RCX (to bring this back to oblego), as it
is a pure interpreted language and the stack costs for it would be huge.
