Is anybody concerned that lisp/play/tetris.el might be a trademark
infringement?

Yes, it does, with CVS Emacs as of 05/02/2007.  Originally, I couldn't
reproduce it on demand.  That's why, originally, I was asking for help to
track it down.

But, messing around just now, I've finally managed to do it.  I can't say
that these are the only way of reproducing it, as I've seen this
misfontification in a variety of situations that do not look obviously like
these.

1.  The goal is to write the code snippet:

int main() {
  foo();
  bar();
}

emacs -Q foo.cpp
int SPC main() SPC { RET } RET C-p C-o bar();

OK so far.  Now to insert the "foo();" line:

C-a C-o foo

At this point, "foo" is fontified as a type, and "bar" as a variable.  OK.
Now:

()

The fontification of "foo" and "bar" disappears.  OK.  Now complete the
snippet:

;

Now "foo" is fontified as a variable.  This is wrong.

2.  Here's a variation.  This time, the goal is to write the code snippet:

int main() {
  foo(fubar);
  bar();
}

emacs -Q bar.cpp
int SPC main() SPC { RET } RET C-p C-o bar();

OK so far.  Now to insert the "foo(fubar);" line:

C-a C-o foo(fubar

At this point, "bar" is fontified as a type.  Not sure why, but still.  Now:

);

Now "bar" is fontified as a variable.  This is wrong.

What is worse is that in both cases I cannot get rid of the misfontification
without turning Font Lock mode off and on again.

I hope this help to fix The Most Annoying Fontification Bug Ever.  Simon.

Thanks.

Don't poke the monster.

Uh-huh, he's woken.

Yes, unfortunately, I think that if you try to learn types on-the-fly then
you will always be vulnerable to this sort of problem.  The issue is that
cc-mode needs to know as soon as a change invalidates it as a candidate type
(ie, deletion of some/all of the text "foo" or interruption of the
whitespace between "foo" and its candidate identifier "bar").  I can think
of a few ways you could attempt to do it, but they are a bit intensive and
far from simple.

Perhaps cc-mode should only try to learn types when fontifying the whole
buffer?

Simon.
