Comment:

 Now that this ticket is back to mitar's original request.  I think that
 this feature request could be implemented (creating a meta-interpreter) on
 the back of #4459.

 By introducing `bind` at the interpreter level we can invoke side-effects
 on a line-by-line basis within any monad construct.
