Effective Haskell: consider formatting variable names as code to make sentence easier to read (page 89)

The description is “pairs of a and b, where a comes from the list of as, and b comes from the list of bs, where a is an element of bs, and b is odd”.

This might be easier to read if “a”, “b”, “as”, and “bs” were formatted in the way function names are in other parts of the text.
