I like the idea of having a defxxx to define a name space as its
consistent with the rest of the API. Thanks Rich.
Regarding the name, actually, I didn't realize plural angle till
it was pointed out. However, I feel defns is a good enough name
as there isn't a 's' being used for plural by any of the other defs to
my knowledge.
If a need arises to use s for plurals in some future def it may
become confusing.
defnamespace will make be inconsistent with 'ns', 'in-ns' etc.
Putting a - as 'def-ns' will also make it somewhat different from
the other defs IMHO.
