synopsis: A fold function for Bool
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.
