xform is being applied after the default mapper on proto-map->clj-map

[thiagocarvp]

I'm trying to use the xform argument on the proto-map->clj-map function to handle proto-maps that have fields using one-of.

However, the xform is being applied after the default mapper, so it cannot access the proto-map. Is this order supposed to be this way?

Line 122 in df3f76f

xform (comp mapper xform)]

If the xform is meant to be the first transducer, it should be:

(comp xform mapper)
