The Omega code where the direction support in luatex comes from is
already much more advanced than eTeX's \beginR ... \beginL stuff,
so can you please explain why and how TeX-e-Parsi is better?

Due to lack of comments in the tex.ch file I cannot even ascertain
which of the 100 commands deal with directions. Before I can say
anything more about this--let alone incorporate some stuff--I need
to read user (and preferably also developer-targeted) documentation.
