Maybe. I don't know for now. It's only memo.

No, I don't know too. But SLIB also implementing require macro. Maybe
it be another reference.

Sometimes Scheme code consumes much more memory than C, so 
that depends on the situation.

In addition, development cost is also important. If writing in Scheme
is considerably easy, Scheme code sould be used. Rewriting with C later
is always possible.
