   Thanks @Dandandan and @alamb. This will be helpful for me. I am increasingly 
refactoring  some operations to "un-fuse" them actually, where we have 
complicated operations in a for loop that limits vectorization. I'm finding it 
faster to break them into stages, apply predicates, and build up boolean 
selection vectors to do a final output at the end. I'm hoping to adopt this API 
in the future.
