The way it'll work is if you have:
@foo = @bar ^+ @baz;
that'll boil down to a single interpreter op:
add foo, bar, baz
When the add vtable method for the array bar is handed a whole array as its
second parameter, it does a piecewise add, as it needs. Non-default
behaviour will require list decomposition and mapping and stuff, but
that'll be just a few ops too. (map will be a single op, for example)
