<lazybot> => "([f] [f & args]); trampoline can be used to convert
algorithms requiring mutual recursion without stack consumption. Calls
f with supplied args, if any. If f returns a fn, calls that fn with no
arguments, and continues to repeat, until the return value is not a
fn, then returns that non-fn value. Note that if you want to return a
fn as a final value, you must wrap it in some data structure and
unpack it after trampoline returns."
