I’m trying to do something seemingly simple with RecipesBase thats turning out to be a bit of a headache. Is there a pragmatic way to make a function that returns a call from an @recipe plot function?

Here is a toy prompt:

```
using RecipesBase
using Plots
struct PlotIt
fn
end
(PI::PlotIt)(x) = PI.fn(x)
@recipe function piplot( Shape::PlotIt, x )
x := x
y := Shape.(x)
seriestype := :path
()
end
struct PlotOpposite
fn::PlotIt
end
(PO::PlotOpposite)(x) = -PO.fn(x)
```

So what I want to do is something like the following:

```
@recipe function plotopp( PO::PlotOpposite, x )
return piplot(PlotIt( y -> -1 * PO.fn.fn(y) ), x) #Return the result of function call to piplot
end
```

I know there are ways around this but I find this kind of pattern to be interesting. Figured I’d learn something making a post like this.

```
x = 0.0:0.1:(2pi)
PI = PlotIt( sin )
Plots.plot( PI, x )
PO = PlotOpposite( PI)
Plots.plot( PO.( x ) )#Desired outcome
Plots.plot( PO, x ) #Broken
```
