Type : defect
Priority : minor
Component : Script semantics
Version : 5.91
Pages : 27
Dependencies: None

Summary:
--------

The current description of script semantics does not
allow multiple return values for expressions preceding
definitions. A small typo is also pointed out.

Description:
------------

The draft states: "each <expression> that
appears before a variable definition in the script body
is converted into a dummy definition (define <variable>
<expression>), where <variable> is fresh identifier."

(First a typo: "variable definition" should presumably be
                be "variable or syntax definition".)

Thes description does not allow <expression> to return
multiple values. This restriction was presumably not the intent
of the authors.
