There are several applications that involve finding i such that key[i]
<= query < key[i+1] where the keys are sorted and unique ... perhaps
with a huge sentinel key at the end. Examples include sliding-scale
taxes, and looking up prices for shares or managed funds. The code to
do this in Python using the bisect module is about as clear as the
equivalent SQL :-)
