builtin slicesopSliceAssign (and opSliceOpAssign) understanding 
ranges as source operands is a good idea. I might even see if I 
can implement it.

Lowering array operations to lazy ranges seems like a huge can of 
worms. Not so keen. Lazy array ops are great, but I don't see it 
working out as a builtin feature unless it had it's own syntax.
