Support destructuring maps with namespaced keywords

Description

Current :keys destructuring expects symbols and creates local bindings based on those symbols. This works fine with maps that use non-namespaced keyword keys. This enhancement is to add support for destructuring maps with namespaced keyword keys.

Approach: Allow keywords (with or without namespaces) in :keys destructuring. Destructure to bindings with the name of the keyword (namespace is ignored).

A potential point of confusion here is illustrated by the following:

To get the answer 3001 one needs to remove the conflicting binding :y/b. Maybe this is not a big deal, but expect questions for the next 100 years.
