OK
You could store keywords in vars if namespaced keywords really bothered you.

My main concern is that when using reader macros for metadata I have to
fully qualify it. For instance, I must write:
(defdatatype
::Streams
Nil
(^:ml.datatypes/lazy Cons elem stream))
instead of
(defdatatype
::Streams
Nil
(^:lazy Cons elem stream))
But I suppose the benefits of namespacing outweight these inconveniences.
