It's not just Boost - I've found a good deal of resistance to any
'non-obvious' code in safety-critical projects (I tried to get some code
into a project that included template metaprogramming to optimise
communications operations - I didn't succeed), which I can kind of
understand. Without good documentation, it's not easy to pick up and, in
addition, as all verification has to be performed by someone other than the
person writing the code, the burden of understanding the code is required
of several people, not all of whom are necessarily experienced C++
programmers (or C++ programmers at all, for that matter).
