Sorry, this is the stripped down version of the cause of the bug I'm
finding various places:
(let ((a 1))
`( ,(begin (set! a 2) a)
,a))
-> (2 1)
Wouldn't it be better if this one returned (2 2)?
Also, I'm seeing different behaviour in the order of evaluation between
1.6.4 and 1.7 (doesn't have the code available now). I think that is
really bad actually...
