Can you mention the part of R5RS that mandates a REPL?
I didn't say that R5RS mandated a REPL. I said that the REPL had
been removed from the spec. Note that LOAD, for example, is gone.
I can't find a reference right now, but I recall reading that a
decision had been made not to address interactive use any more
because the authors couldn't agree on the semantics. Please forgive
me if I'm misremembering.
In any case, one of the great things about Scheme and Lisp in general
has always been their support for interactive, experimental use. If
we have to patch an entire program before any part of it can be run,
we will have lost another part of this interactive, experimental nature.
