May 26	comment	Normal \relax vs. frozen \relax Generally speaking, `\ifx` only looks one level deep: it checks whether all tokens have the same indices into the equivalence table, but does not check whether they have the same meaning. The same works with `\let\foo=\relax`: Now `\foo` is a token with the meaning of `\relax` but a different name.
May 26	comment	Normal \relax vs. frozen \relax On the other hand, `\expandafter\ifx\x\relax` is true. This works for all primitives that have a frozen version and therefore appear twice in the equivalence table. With LuaTeX, you can create additional copies of primitives using `tex.enableprimitives`, and they show the same behavior.

Apr 3	comment	How to lower the superscripts (and raise the subscripts) AFAIK setting the extended font dimensions is ineffective in XeTeX (they don't actually get applied), so you can do this only in LuaTeX (`\Umathsupshiftup=12pt`).
