This needs me to wrap every function into a function object and then instantiate that function object using an aggregate syntax. This is awkward. I need something automatic for functions.

I need something which can work with expressions like

1 >> &f >> &g >> &h

where f, g, and h are ordinary functions. Is that also doable in Proto?

TIA,
