Subject: [Boost-users] BOOST_RESULT_OF_USE_DECLTYPE and Boost.Optional ?
From: John M. Dlugosz (mpbecey7gu_at_[hidden])

I turned on BOOST_RESULT_OF_USE_DECLTYPE and used boost::result_of because the
std::tr1::result_of that comes with VS10 doesn't use declspec at all and thus doesn't work
right with lambda functions.
This passes my unit tests, but fails on a piece of code that has a function returning an
instantiation of boost::optional.
It seems confused as to whether the value held in the optional is as-specified or has a
reference added to it.
I wonder if this is a specific issue with optional that might be
addressed/worked-around/patched, or perhaps there is a way to enable declspec-based
testing just for the code that wanted it and not globally?
