#1155: values and the scrutinizer

     Type:  defect             |      Status:  new    
 Priority:  not urgent at all  |   Milestone:  someday
Component:  scrutinizer        |     Version:  4.9.x  
 Keywords:  values             |  
-------------------------------+--------------------------------------------
 The scrutinizer complains a little when faced with values under certain
 circumstances.  Here are some examples:

 {{{
 $ echo '(module val () (import scheme) (values))' > val.scm

 $ csc val.scm

 Warning: at toplevel:
   expected in `let' binding of `t10' a single result, but were given zero
 results
 }}}

 {{{
 $ echo '(module val () (import chicken scheme) (and-let* ((#t))
 (values)))' > al.scm

 $ csc al.scm

 Warning: at toplevel:
   branches in conditional expression differ in the number of results:

 (if #t (values) #f)
 }}}

 Of course, those warnings make sense, but I wonder if there is anything we
 can do to improve that situation.
