Overview

Essentially the same thing as MethodStep with AssemblyStep semantics.

Because we don’t have a clever way to determine that you might want to create an assembly line out of wrapped methods, you need to use the conveneince method Pipeline#assembly_step, eg.

PiecePipe::Pipeline.new.assembly_step(:add_seatbelts)

Currently only supports arity-1 methods: the parameter will be the inputs Hash, the return is expected to be a Hash that will be produced via AssemblyStep#install.

TODO; add support for arity-2 method wrapping to allow for zero-or-more #intall calls
