I know. I elided including the nonexistent `nonlocals()` in there. But it *should* be `lngb()`. Or call it scope(). :-)

I think that to match the normal name resolution rules, nonlocals()
needs to slip in there between locals() and globals(). I realise that
there actually isn't a nonlocals() function (perhaps there should be?).

I like the concept, but not the name. Initialisms tend to be hard
to remember and rarely self-explanatory. How about scope()?
#letsgoblues!
scope(**kwargs), lngb(**kwargs), lookup(**kwargs) could allow for local attr override.
