I'm getting the sense that the biggest head wreck for people here is
the idea that optional and future are the same thing. As in,
literally the same implementation code with the same API.

I've tried to not deviate from source compatibility unless there was
a good reason. Either from optional, or expected. My hope is that
with a bit of template aliasing the implementations could be swapped.

Regarding your comments that WG21 is a lousy place to design
libraries, I agree in the strongest possible terms. Boost once was
the place to playpen exciting new C++ libraries - if you read this
mailing list back in 1999-2001, there was a palpable excitement here
as people tried new things and showed one other what could be
possible. Rather like in the Rust mailing list nowadays.

especially since Dave left. It doesn't help when members of the
steering committee conspicuously fail to perform their duties, and
specifically disavow taking any leadership position except to
intentionally prevent and inhibit change.

I strongly support your earlier comments Tony, and your rationale,
and it's long overdue for an Boost.Experimental library distro. If
Boost can't and won't do it, someone else should.

(For the record, it won't be me, I'm likely going to be unemployed
next week and my plate this year is too full. But I'll support anyone
who does best I can).
