-%D There is a probably rather useless \type {\expression} command that can mix \LUA\ numeric
-%D expressions with \TEX\ commands (for as far that makes sense) that works like this:

-%D \mathchardef\foooo   1234

-%D
-%D \expression string.format("\letterpercent f",\elapsedtime/50000) \relax
-%D \stoptyping
-%D
-%D The final \type {\relax} is mandate because we also accept spaces. Of course we
-%D could have avoided it by using outer parenthesis but this is cleaner anyway.
-%D
-%D The \LMTX\ version supports te \type {xmath} and \type {xcomplex} functions and
-%D therefore one can have expressions that don't work in \MKIV.

-% maybe: \let\texexpr\expression
