relax, genius. I'm not proposing that we drop cut. I'm asking why it
has to be written in C instead of a higher-level language.

sed is not trivial to write in awk. there is nothing you can't do,
obviously, because awk is turing-complete. I realize that you're just
being a shit, but sed is a text editor, and cut is a thing written for
people who couldn't be bothered to learn things. In fact, I'm fairly
certain I could implement cut in sed.

I'm going to ignore your "take the concept to the extreme" straw man
because it isn't interesting. I'm asking for clear cases where binary cut
is obviously superior, and not a bunch of whining because you're used to
it being an individual binary. If you can't deliver, maybe Steven
Blatchford can?
