One possibility:
- make adaptor expressions return const rvalues. The const rvalues will bind to T& arguments (where T is a template parameter) by deducing T to be const.
I don't like this one.
For the record, Boost.Proto uses the const rvalue trick extensively. It works well in practice, in my experience.
- make even the const_iterators for such adaptors mutable (writable) iterators
This accurately reflects the fact that such adaptors don't own their values.
Seems reasonable.
