[texhax] \MakeUppercase vs. \uppercase

[Philip TAYLOR]

Dear Ky Anh -- The TeX primitive \uppercase is /very/ anomolous
in terms of the timing of its operation (you would need to read
/The TeXbook/ in great detail to completely understand its
operation) which is one reason why Leslie Lamport (or possibly
Messrs Mittelbach et al -- I don't know who actually implemented
it) provided a more robust and consistent replacement for LaTeX users.

Even serious plain TeX hackers sometimes have problems understanding
the exact timing of \uppercase, so I wouldn't worry too much if you
don't : just use the LaTeX equivalent instead!)
