I don't know either about the difference of those two...
Guile provides some procedures like procedure->syntax, so

We have to be careful choosing API, though. (like import-*)

Right.  Thanks.

There are a lot of bugs in that code... (It doesn't work.)
I'll fix them and release the next version soon.

OK.  I didn't know that.  Thanks.
