LISP: selecting with bias from a set of options
#|
for both proj2 and proj3 you'll have to select "things" weighted by some
bias on how much we like "things" (e.g. stinky roads we do *not* like)
it uses a set of useful techniques that i'll walk us through on thursday
the following code is my generic "pick with bias code". here's the output
of the !pick1 and !pick2 demo. each demo is 10000 picks, biased by
the weights within the bias
CL-USER> (!pick1)

LUA for loops (in LISP)
#|
The LUA programming language supports iterators.
The LUA for loop takes some generate function and asks it to
produce a function that can return the next item.
A loop is then entered. The next item is generated. If it
is non-nil, then the body of the loop is called to consume
that item.
