You seem to be suggesting that a dedicated function will reduce
boilerplate commands, resulting in more readable code.

You COMPLETELY failed to even read the reporter's message, which
specifically stated "In order to reduce forks and make some tasks a lot
quicker [...]"

Very plainly, the reporter does not care how much code is used, but does
care that $() forks a process. It's literally the entire point of the
discussion: to replace forking with redirection to fifos.

Now, you can argue that this should or should not be a goal, but it's
quite silly to conflate the goal with "your goal could be achieved by
using a function".
