[OT] std.bitarray

[BCS]

Could you /please/ include the "reply to" line in the text of your posts. 
Most clients seem to add it by default and it makes it much easier for people 
to find replies to there posts. (I have a filter set up to mark post with 
my username so, in my case I'd guess that without that line, I'm about 3-5 
times more likely to not see a reply.)

BTW the following line is the "reply to" line:
