Is this library Vc 2.0?

[bernhardmgruber]

Hi! Your previous library Vc promises that after successful standardization of std::simd, development of Vc will be rebased onto std::simd under the name Vc 2.0. However, I have been watching vir-simd for a while now and started to wonder whether this project is starting to become Vc 2.0. So I have some questions:

• Is vir-simd just a prototyping playground for proposals around std::simd or is intended as a solid implementation of std::simd for people stuck on older compilers?
• Would you advice against using vir-simd in production as a replacement for Vc 1.4? Some people at CERN are looking for an upgrade path.
• How does the std-simd repository compare to vir-simd?

Depending on your answers I may want to advertise vir-simd on the Vc repository. Thx!
