Giuseppe knows better, but I'm not sure this is really a bug. Your global
direction is still TLT. (J and Y may have changed things for 1.23 but that may
or may not have been the wise thing to do.)  Unfortunately TLT is largely
hardwired in these high-level formats. What we really need (as Hans pointed
out on the ConTeXt list) is a model for bidirectionality with respect to these
different elements. So there are two questions:

1. What should be the effects of local commands like \pardir TRT
& \textdir TRT?

2. What changes do LaTeX and ConTeXt need to make to fully accomodate
bidirectionality?

As I learned in a complicated bi-directional project recently, the answers are
not necessarily trivial.

P.S. I've use \parshape in Lambda long ago (Omega1.15) with no problems.
