Some of the concerns are implementation issues, and some of the concerns
draw out the requirements. Requirements:
0 Save the programmer from making unnecessary keypresses
1 Don't destroy the programmer's source files
2 Don't demand that the programmer change their sequence
3 Don't distract the programmer

Absolutely. The way I see it, here is the difference between your
reply, and the replies from David Laight, der Mouse. : the other
replies assume that a team of ponies will be necessary to provide the
desired function, and they ask which ponies are really necessary, point
out which ponies are necessary but missing, tell which ponies are
already present, and so on. Those replies are helpful. The gist of
your response is "Be realistic, this is going to take a bunch of ponies
whose color, markings, and provenance we do not already know." You've
told us that we need ponies, but we'd already established that, and
we're already counting the ponies that we do and do not have.
