TeX macro language is an unmitigated disaster for writing macro packages.
Arcane parsing of arguments, arbitrary restrictions, insane char code
conventions turn simple things into complicated endeavors. No
debugging support either. TeX macro language was a good choice for
hardware in 1988 but now one can do much better. I do most of my
writing in LaTeX and cry out every time I have to do a presentation
with Beamer and animations:-)

If Lua can help writing TeX packages that would put LyX like efforts
on more solid footing.
