as pointed out elsewhere in this thread, `"a" or "b"` evaluates to "a", which kind of makes me think that `a | b` (with a and b as dicts) would take values for overlapping keys from a, not from b. The dict literal with dict-splats conveys a sense of ordering that makes the behavior of taking values for overlapping keys from the lattermost dict make more sense to me.
