@ -869,3 +869,21 @@ Time to clean up for v300. Let's see if we can get begin and begin0 working.
*************
Okay, it turns out that begin expands into a let-values with empty bindings,
so I'm working on getting this going. With this addition, the annotation for
'let' is a complete monster, chewing up a substantial fraction of the annotation
code all by itself.
Also, I've come across a design optimization that improves if & set!, which is
this: there's no reason to have if-temp & set!-temp. Putting these inline
is a great improvement: it reduces code in the reconstructor, in the annotator,
all over the place. The caveat: I haven't finished it yet, so who knows what
kind of horrible thing will crop up.
The architecture change here is that we need a new kind of break that's like
a normal-break (blecch! terrible name!) but carries a value along with it.
I'm going to call this the normal-break/value break. Blurrch!
