Well, yes, that is the beauty of macros. What is holding you back from the Arc example is that it makes you nervous -- how can it work?! I do not see all the moving parts! But then when we are programming heads down do we really want to see all the plumbing? Macrology is all about hiding the boilerplate so we are looking at just what matters. But yes again: make sure your macros (or the ones in the library you choose to adopt) work. :) Once you have satisfied yourself of that, as a developer you are in a much better place. My 2, anywho.
