Not at all. My criticism, if any, is directed to the idea that
"educating" is always the best answer. People often don't want to be
educated, and the reasons (lack of time, interest, whatever) are as
subjective as perfectly legitimate.

I, in fact, agree with you. We differ in that I think goto-line is a
perfectly reasonable thing to do in many situations, and its relation
with compiling, etc. is only marginal.

I was referring to things like compile.el; in a few cases, they chose
the same path I do (not because of my influence, just because they
didn't want to spend time reading the manuals): compile in another
console window, use Emacs to edit, fix, save, and back to the console
to compile again. Certainly they do use goto-line; in fact, binding it
to a key was one of the first things they asked me to do (the other one
is setup an f-key to do bs-cycle-next, they won't touch switch-to-buffer
and list-buffers with a ten feet pole).

Sure.

The falacy here is that you consider next-error much more useful than
goto-line. I don't. I'd bet for users in general, many of which will
never compile a thing, going to a line is orders of magnitude more usual
than searching for an error.

I have a friend (a bookstore owner) who manages all client orders through
an ASCII/Perl/MultiEdit setup (MultiEdit is a programmers' editor). He
doesn't program at all; he writes orders in ascii files, process them
with Perl scripts, send the resulting request to his suppliers, and on
arrival of the goodies, he manually edits the ascii files to remove
items and classifies the items in boxes for his clients. He won't know
what next-error does, but he uses (the MultiEdit equivalent of) goto-line
many times a day. As you've said earlier, you and I and most people
around here are not statistically normal Emacs users (I think).

Not a good mnemonic, "gresca" in Spanish means something totally
different, I'm afraid ;)

Or, perhaps, it's just that there are not alternatives for a simple
task: going to a line. Not an error line, not a line containing some
text, just to the line numbered X.

Sure.
