Users may not see the warning that insertPosition definitely needs to be
inserted at the leftmost position, which can cause undesired behaviour.
Having a combinator that handles this automatically seems like a sane
idea.
Fixes: https://github.com/xmonad/xmonad-contrib/issues/709
(Note that `docs` wasn't changed since it already inserts itself
rightmost.)
This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
