This is what r7rs requires: In a define-library the only visible
bindings are those explicitly defined or imported.  OTOH at the top-level
"For convenience and ease of use, the global Scheme environment in a
REPL must not be empty, but must start out with at least the bindings
provided by the base library."

One of the things I had to explicitly work on for the R7RS functionality was
making sure the define-library "environment" starts out empty.

The following should work:

(import (only (kawa lib syntax) synchronized))

However, that will not work if synchronized is moved
from the kawa.lib.syntax class.  That sort of thing occasionally
happens, as I consider the specific implementation class an
implementation detail.

That is why as need to define some library such as (kawa all) or
(kawa jvm). so you could (import (kawa jvm)) - as I mentioned in my
previous message.
