<a name="line-6"></a> This module supplies a method for writing 'Biplate' instances more easily.
<a name="line-7"></a>
<a name="line-8"></a> To take an example:
<a name="line-9"></a>
<a name="line-10"></a> > data Expr = Var Int | Neg Expr | Add Expr Expr
<a name="line-11"></a> >
<a name="line-12"></a> > instance Typeable Expr where ...
<a name="line-13"></a> >
<a name="line-14"></a> > instance (Typeable a, Uniplate a) => PlateAll Expr a where
<a name="line-15"></a> > plateAll (Var x ) = plate Var |- x
<a name="line-16"></a> > plateAll (Neg x ) = plate Neg |+ x
<a name="line-17"></a> > plateAll (Add x y) = plate Add |+ x |+ y
<a name="line-18"></a> >
<a name="line-19"></a> > instance Uniplate Expr where
<a name="line-20"></a> > uniplate = uniplateAll
