Yes, I was just trying to get a better grip on what you were thinking 
with two view types.

If there's no big usecase for arithmetic operators on them in the first 
place, I see no harm in having a 
i_really_know_how_simd_works_now_let_me_shoot_myself_in_the_foot 
directive enabling SIMD on views, enabling us to simplify and only have 
one view type (i.e. it wouldn't "switch" semantics, only allow 
semantics, which seems like a safer directive).
