Ugh, it seems that you haven't read my strong objections a few hours
ago.

It's still not clear to me why this can't be handled in a front-end.
Compare this to correct English grammar, where you have to uppercase
certain words.  Many people use spell-checkers to fix typos, and
\foobar vs. \fooBar belongs exactly into this category.

I would rather like to have this an error, with exactly the same error
message.  As mentioned earlier, using a Levenshtein distance or
something similar it should be possible to catch more serious typos in
the same vein.

Please no heuristics.
