Hi Jochen,
To be honest, I have no complex examples in my mind. Maybe it will be
good for DSL(We can think `|>` as a big arrow drawn by | and >):
```
clothes |> clean |> dry |> notify
```
I ran the code you provided, error occurred as you expected, but we
wish it could run well. We have to refine the implementation...
groovy> class X {
groovy> private bar(){1}
groovy> def b = this.&bar
groovy> }
groovy> println new X().b()
groovy> class Y extends X {}
groovy> println new Y().b()
1
Exception thrown
groovy.lang.MissingMethodException: No signature of method: Y.bar() is
applicable for argument types: () values: []
Possible solutions: tap(groovy.lang.Closure), wait(), any(), wait(long),
any(groovy.lang.Closure), is(java.lang.Object)
Cheers,
Daniel.Sun
