[luatex] tex.extraprimitives() and Umath primitives

[Khaled Hosny]

Hi all,

Is there a way for tex.extraprimitives() to return only Unicode math
primitives? I think not, but I thought to ask anyway.

(Next XeTeX now supports \Umath* names for the primitives to be more
compatible with LuaTeX, but it will not be much useful for LaTeX users
as they are named \luatexUmath* there, and I'm looking for a clean way
to solve it.)

Regards,
Khaled
