I have a question about the Boost.Optional documentation, explicitly
about the paragraph on "Requirement Portability"
Is this really true? Can someone please provide any reference to the
standard? And if it is true, would that mean that for *any* map<T,U>
requires that U is DefaultConstructible as this is required by
map<T,U>::operator, regardless of whether operator is used or not?
(It's actually a little bit different because the Boost.Operators
library uses friend functions).
I have read 14.7 and discussed it with two colleagues, and we agree that
the documentation is wrong and that this paragraph should simply be
removed, but I would just like to check that I haven't overlooked
