Comment (by simonpj):

 > As currently designed, however, TyPrec doesn't fit neatly into this
 PprPrec paradigm

 Yes it does!

 The Note says that currently `FunPrec` and `TyOpPrec` are treated as
 equal.  So we could say
 {{{
 funPrec = Prec 2
 tyOpPrec = Prec 2
 }}}
 We have two names so that we can later give them different precedence if
 we want.  As the note says
 {{{
 But the two are different constructors of TyPrec so we could make
 (->) bind more or less tightly if we wanted.
 }}}
 Seems a neat fit to me.
