This issue is to document functions that are in some of the vector modules, but not others. I will update and add missing functions as I find them:

Not anywhere, but nice to have:

• iforM
• iforM_

Mutable modules should probably re-export PrimState and PrimMonad so it's easier to write PrimMonad generic code without adding the additional primitive dependency and an extra import.

Data.Vector.Storable:

• imapM
• imapM_
