I guess someone should look at the other uses of `eval-buffer` to figure
out if that's the case.
Another approach might be to check if `lexical-binding` is set
buffer-locally and if so to obey it without even checking the
`lexical-binding` cookie.

I can't remember how we ended up with this, but I strongly suspect it
has to do with the use of `eval-buffer` in `load-with-code-conversion`,
which is the most common use of `eval-buffer` (in dynamic counts, not
static counts, of course).

Is it good in any other case? I mean, what's the logic behind ignoring the current value of lexical-binding, but heeding the cookie? let alone defaulting to dynamic binding if there's no cookie? If the reason is backward compatibility, I think I'd like to see the details: where would changing this cause problems? And note that this aspect of the eval-buffer's behavior is not documented in the ELisp manual, which is also not a good thing.

Oh, me neither, I had forgotten/missed that discussion. What I really meant is that we shouldn't be adding a lexical binding cookie to the file. -- Sean Whitton

I agree it is a bug. C-c C-e calls `eval-buffer' which "ignores the current value of the `lexical-binding' variable. Instead it will heed any -*- lexical-binding: t -*- settings in the buffer, and if there is no such setting, the buffer will be evaluated without lexical binding." Not good in this case. Michael.

Please provide a rationale for your suggestion, because without that there's no way of reasoning about this.
