Is a distinction between function's and macro's namespaces intentional?

[kariya-mitsuru]

In the current implementation, macros have their own namespaces.

I think this behavior is consistent perfectly, but the common lisp has no macro's own namespaces, it shares namespaces with functions and macros.

Just I don't have knowledge about common lisp. So lm is possible to be merged into lf.
