@hdu: Generally I agree with you on the subject of changing bidi properties. But
in the case of brackets and parentheses similar problems repetitively seem to
pop up. Therefore I feel the need to rethink the current situation once more.
Some of these thoughts don't relate directly to this issue, but I think the
broader view will also contribute to the current problem. 

Paired parentheses contain the notion of opening and closing. This is expressed
visually, but only if both parentheses are directionally interpreted in the same
way. So we mainly encounter problems in cases, where one bracket has an
unambiguous bidi context and the second one is on the boundary of bidi runs. I
think these cases could be improved by applying the unambiguous context to the
pair bracket.

The example to this issue is different, because here we have a symmetric
situation (only one direction inside the brackets). Directionally-speaking it
does not make a difference, if the brackets are assigned to the outer or inner
run. They will swap their places, but the visual result is the same.
Typographically, there is a difference: The brackets could belong to the inner
or outer script and would be displayed in the corresponding font. In any case,
as you stated before, bracket and enclosed word shouldn't be separated even if
they belong to different runs.

In the current situation the paragraph direction determines the script type of
the parentheses in the latter cases. In these paired situations, the script type
could also be determined by the enclosed script or the outer script. Each mode
of interpretation could lead to subtle differences in the visual appearance
(depending on the fonts chosen). But I think it is also a more general
(philosophical) question: Where do the brackets belong? To the outer or to the
enclosed?
