This is not an ad hominem attack. I'm criticizing your choices. You've
asserted that those objecting to your choices are ignorant of modern
C++. You've asserted that "Some Boost developers are ideologically and
irrationally attached to "how things are done around here".
I dispute all of the above assertions. There is not evidence for them -
how could there be as they are not true? And even if they were true,
they would in no way be an argument for the library, up ending boost via
the inclusion of a single very small and simple library or anything else.
You've used these assertions as a way to discredit the arguments of
those whom you disagree. This is wrong. Worse, it is contrary to your
own interests. Many of us want you to succeed as we want many to
succeed. Many of us much appreciate your efforts to contribute to
boost, boost-gsoc, conferences etc., even though we disagree with most
of your ideas. Many of us have tried to be constructive in attempts to
make outcome a useful addition to boost. Assertions such as the above
diminish this reservoir of good will. It is not to your advantage to do

This is an assertion that many of us question
But this was not my point or main concern. It was that this is out of
scope for a boost library to change boost in this way. This is attempt
to inject into boost a whole new way of doing things which many us don't
have any faith in. It touches on our usage of Git, CMake, and other
tools which are questions which are orthogonal to the acceptance of the

Right. I think this demonstrates my point. We're not reviewing the
source code of outcome here. You're advocating a replacing boost with
something better. OK - but this it out of scope for the review of output.

LOL Right. It IS an opinion not a fact. That's why we're having the
argument. Of course I would disagree that my arguments how no technical
basis and you are free to so characterize them, but I'm doubtful it
helps you in anyway.
Although it's implicit in my comments, I'll be explicit about my suggestion:
a) submit outcome in a way that looks like the rest of boost libraries
so it would be evaluated by the same criteria that other boost libraries
b) Make you're own Nial-Boost-Lite repo which applies you're
pre-processing stuff to all the boost library you want to include. It
could, if convenient, include any or all of boost libraries as
subprojects. I would expect that you could find a way to generate this
automatically from any C++ header source. See how that flies.
And there is precedent for this. I doubt anyone would be surprisd at
this point that I created the Boost Library Incubator as my prototype of
Boost 2.0 I can't say it's been successful in achieving this goal,
though it has some useful value.
