You have an attitude problem.  I will only hold that against *you*,
though, and not against your *argument*, just as soon as you present one
that is worth the time I spent reading it.

Good for him.

I take it "wonky" is some technical term with which I am not familiar.

Really?  What question did I dodge?  If you repeat it, and it is not
completely full of crap, I'll be happy to address it directly.

What does that have to do with it?  I never said otherwise.

I guess that depends on how you define "feature" -- but I don't use csh
without the t much, anyway, so that statement is not directly applicable
to the interactive shell I have been using most of the time.

Also . . . feature counts are not measures of quality.

Maybe so.

I'm not sure why you're bringing these things up.  "They both have
instances of the same basic mistake -- implementing functionality that
already exists in standard utilities."  Well, great.  I'm not sure how
that has anything to do with mksh being better in all ways.

I have to wonder if you even understand your own arguments when you say
things like this.
