Hi everybody,

is it planned to extend the dynamic_bitset in the near future?
I would consider the implementations of the following functions to be particularly useful:

find_last();Â  // position of most significant bit
find_previous(size_t pos);Â  // like find next, but in the other direction

find_first_not();Â  // position of first unset bit
find_next_not();Â  //...
find_last_not();Â  //...
find_previous_not();Â  //...

further, views would be nice, so that one could act with bitwise
operation only on a certain subset of the bitset.

and last but not least -- I know that might be beyond the scope of this class --
arithmetics would be nice, so that one could directly copy e.g. the algorithms form bit-twiddling hacks.
( *of course* they should also work on views ^^ )

I know thats a lot, but it would certainly be helpful.

Thanks in advance and
best regards,
David
