%description
The `bool' function allows folding over boolean values.

This is comparable to the `maybe' or `either' functions on their respective
types.

The `bool' function is a replacement for the build-in 'if then else'-syntax.
However, since it is a function, it can be partially applied and passed around
to higher order functions, like so:

> ghci> :m + Data.Bool.Extras > ghci> let yesOrNo = bool "no" "yes" > ghci> map
yesOrNo [True, False, True] > ["yes", "no", "yes"]

Note that the arguments to `bool' are in the opposite order of the 'if then
else'-syntax; First the false value, then the true value, and finally the
boolean.
