Unfortunately not yet; but i have the distribution since
yesterday.  (The git(1) pack is 121 MB.  And what i've seen before
belonged to go, yet i wrote Plan9 since it seemed to have a common
origin.)

May be worth taking a deeper look into a system that works for
non-english.

Btw. i thought i was so smart due to my "Ctx" objects for bracket
expressions, format string conversions etc. -- and even said so --
only to find out that on Plan9 there existed something rather
similar years before!  Pretty awkward.

yea yea, maybe: i'm not familiar with something that just works,
i'm using BSD for such a long time.
Looking into upas doesn't make me much happier, too.  Sigh.
