IMHO (PicoLisp) Namespaces _are_ "name" prefixes, for example "pg~" instead of "pg-".
[de pg []] # Empty Namespace.
[de pg~sym ~...]
Unfortunately Namespaces are not Association Lists, or Property Lists.
Therefore they can not be processed by predefined procedures. I must point
out that Namespace interface is not exposed (as PicoLisp procedures), like
"get" and so on for Property Lists!!
