If you don't call too many Prelude functions then a _possibly_ cheaper
solution is to just duplicate the code for Prelude functions which
you /do/ use. Put them in some dummy module if necessary and import them
instead (maybe hiding the Prelude imports if you don't want to rename

This gets a bit messy (nigh impossible) when you want to see calls made
to derived instances of type classes, but you may not need that level of
