cheers for old code

No one ever said eval is evil, if you're using it solely to consume the output of a shell builtin functionality specifically designed to produce eval-safe text.

In fact, greycat's official stance on precisely that can be found here (and agrees that Chet's example is reasonable and correct):
https://mywiki.wooledge.org/BashFAQ/048#Examples_of_good_use_of_eval

Opinions differ on whether it's evil to try writing your own text for eval'ing, since most people doing so seem to get it wrong. But that's neither here nor there.
