If the input/output ranges are easy to implement(so it's just
reading/writing an element, keeping an index for the writer and
another for the reader, and reseting it, isn't it ? So if
(isInputRange!MyCont && isOutputRange!MyCont) then it's a
"Deque", right ?).
The bidirectionnal ranges or the forward ranges become more
difficult to interpret with the idioms I
use(Insert,Add,Remove)...Is this a kind of 3rd plane ("time":
"return to previous state", "make a backup": copy/roll-back -
Could you recommend me the algos from std.algo to test
efficiently my implementations ? (example, if you want to be
sure that the input ranges work then you'd use this...if you
want to be sure that output ranges work then you'd use that
...Some kind of "reference" unit tests ?). At the present time,
each time I try one I get rejected by the template
I'm not sure, if I understand your question correctly, but I
think what you need are RandomAccessRange's (cf.
http://ddili.org/ders/d.en/ranges.html). You can save their state
and access members randomly. However, as far as I know, the range
itself should not be modified while you iterate over it.
