I think the better takeaway here is that the "default" (barest) syntax
isn't always the right one.  There's any number of examples of this:

- Variable expansions, «${foo}».  Scalars need to be quoted; arrays need
  to be quoted and @'d; assocs need to be quoted, @'d, and (kv)'d.  The
  actual meaning of unquoted «${foo}» — expand to all non-null values —
  isn't commonly needed.

- «ls *.txt» without a «--» guard.

- «print -- $foo» without «-r».
