I think that statement poorly phrased when we have a fully functional
and proven working modular Boost proposal in BindLib. It's just a few
libraries supporting it yet, but I claim you cannot call this
"unconvincing" when it works right here and now.
Want to test my proposed solution for modular Boost right now? Do
this from a VS2015 CTP  command box:
git clone https://github.com/BoostGSoC13/boost.afio.git
git checkout develop
git submodule update --init --recursive
git clone https://github.com/chriskohlhoff/asio.git
cl /Zi /EHs /Oy- /Ob0 /MD /RTC1 /GF /GR /Gy /bigobj /wd4503
/Zc:forScope /Zc:wchar_t /W3 test\test_all.cpp detail\SpookyV2.cpp
/DUNICODE=1 /DWIN32=1 /D_UNICODE=1 /D_WIN32=1 /Iinclude /Itest
/DAFIO_STANDALONE=1 /DASIO_STANDALONE=1 /Iasio/asio/include
... and it should hopefully spit out a test_all.exe which has not a
single Boost dependency in it, despite being a 100% Boost library and
still written to use Boost.Test, Boost.Config, Boost.Thread and so
I stitched that together from my test config here so it may be
slightly off, but it definitely works. I am going to set up Jenkins
CI testing for standalone builds later today.
: Only VS2015 CTP currently has a working Filesystem TS. If you
use VS2013 or GCC or clang it'll need to link in Boost.Filesystem.
