(merge & pred-forms)

Source docstring:

Takes map-validating specs (e.g. 'keys' specs) and
returns a spec that returns a conformed map satisfying all of the
specs.  Successive conformed values propagate through rest of
predicates. Unlike 'and', merge can generate maps satisfying the
union of the predicates.
