What's the state of std.experimental.typecons.{wrap/unwrap} ?

Sorry about this, it has stalled because it is really hard to 
work outside the actual std.typecons. As I started digging into 
issues with wrapping range interfaces, I started needing more and 
more private methods, basically copying in all of typcons.

Then it got worse, some of the methods needed a change in how 
they interpreted the type. These changes may make sense for the 
original or maybe not, either way maintaining this second concept 
while expecting a need to merge back into std.typecons became a 
mental roadblock on how to manage it all.

I'm probably in a better mental state now and could push for 
changes in std.typecons, but in the meantime I got married with 
children and don't really do hobby programming (at least not with 
the multi-day mental concentration this would require).
