It was important enough for you to mention twice, and it's one of the
only things your proposal seems to offer over SRFI-7, so it looks like a
key point to me.

What? SRFI-7's PROGRAM form does not change top-level forms any more
than a top-level BEGIN does. You're blatantly misrepresenting SRFI-7

Why not spell "create" as "creat"?

It looks to me like there's an even more basic issue: You don't
understand SRFI-7.

Produce them, then. What you believe is irrelevant.

You're using a strange definition of "already provide it" there.

And your solution is to provide a technically inferior version of the
same facility?
