Whether this is an issue depends on if define-record, define-values etc.
can be macros that expand to "define"s and "define-syntax"es or not.

But given that the name of the draft is "Define-syntax in local lexical
scopes" it seems reasonable to define only the use of define-syntax and
keep the letrec-mixed just as a construct to explain easily the semantics.

BTW, does someone know whats going on with the SRFI process? Why there are
drafts that are expired several months ago?
