[Scheme-reports] Erratum for letrec* definition

[John Cowan <cowan@x>]

I've added the following erratum to the list at
<http://trac.sacrideo.us/wg/wiki/R7RSSmallErrata>:

    The semantics of letrec* should say that evaluation of the <init>s
    is interleaved with assignment to the <variable>s. As written,
    it could be understood as allowing the <init>s to be evaluated
    first in left-to-right order and then assigned to the <variable>s
    in left-to-right order.

Not interleaving the assignments would make letrec* fairly useless.

Any objections?
