There's no reason to use this new thing if you're calling awk, because
awk is an external program.  You might as well just use var=$( awk ... )
instead.

Either way, you're going to fork() and exec*() the external awk command.

That one would give a different result because you're not assigning
anything to REPLY.  If I understand the new thing correctly.
