Thanks for the link and (let do ...) example. Interesting to read.
> macroexpansion time is kind of fuzzy in Arc
Well, this was the point of this post! It is important to know about the "limits" of your macros system. As CatDancer mentioned it, there are differences between them.
The catch phrase "macros are evaluated at expansion time, functions at runtime, ..." is too simplistic and doesn't provide enough knowledge at some point.
