As my colleague Hilmar van der Kooij noted in a previous post, e's "defined as computed" macro capability is a great way to condense repetitive blocks of code into a few easy to read, parameterized lines. Building on Hilmar’s practical introduction, I’m going to ask you to take a step back and look at macros in broader context: specifically, consider that macros allow you to effectively introduce your own language constructs in an almost unlimited way. Whether you stick with a purely practical view of macros, or accept this proposed conceptual view, the benefits are the same: macros are a very powerful tool to help to raise the level of abstraction and facilitate reuse of your testbench.
