Firstly, thanks for the story. I found it very supportive.

I will say I find monad<T> an enormous time saver. I find myself
writing most of my functions since Monad as noexcept, and letting
monad<T> convert exception throws into returned monads. That reduces
the time to implement exception safety hugely by constraining the
paths of execution flow inversion, and has led to a substantial speed
up in my development productivity.

I unfortunately suspect you are right.
I implemented APIBind to solve a local problem I had and tried
proposing it as a bigger solution for wider ills, but few if nobody
here was interested.
But that's okay. It still lets me switch between STL implementations
and API versions very easily, and I make heavy use of that facility
in my automated testing. It's a big win for me here locally. I expect
to be using APIBind in any new C++ library I write into the future.
