At one point the BCs followed their original C++ source by providing a
couple of synchronised forms.

I found that for any serious use I couldn't find a one-size-fits-all
(well, few-sizes-fit-all perhaps) approach that let me build real
apps. Iterators were one problem, applications where the data
structure involves multiple containers was another. I did consider
some shared-mutex schemes (would have involved something like
constraining container instances by access Mutex'Class or some
such). But on the whole it seemed that it would be better to require
people to but the protection _they_ need round their data.
