Must have been a miscommunication on my part. The two couldn't be more 
different.

std.experimental:

- NEW, as-of-yet unproven stuff
- Everything can change without notice
- Intent is to be moved to std when ready, where it ADDS functionality
- No changes that break std

std.v2:

- Fundamentally makes all existing functionality in std available
- Breaking API changes are possible, designed, and announced
- Additions are also possible, designed, and announced, but not 
quintessential (e.g. v2 with no autodecoding and improvements to safe, 
nogc, and nothrow would be a solid release)
- Intent is to coexist with std forever, with an eye toward deprecating 
the previous versions

I'd say any parallel between std.v2 and std.experimental is tragically 
misguided.
