They are currently handled specially (i.e. hardcoded). The proper
way to do it would be to introduce internal special forms and define
the forms you mention as syntax. Another thing for my todo-list.

(##sys#module-exports (##sys#find-module '<name>))

will return 3 values:

1) list of exported names
2) list of exported value bindings (a-list)
3) list of exported syntax bindings (a-list, circular)

Note that this is an internal API, so subject to change. There is no
official module API yet.

There is no public API, but the module-structure returned by ##sys#find-module
is defined in line 1265 of expand.scm, the defined-lists may be of interest,
which you can access with ##sys#slot (or block-ref). The parameter
##sys#currrent-environment holds the currently imported bindings.

I hope this is somewhat useful.
