Draft Version of Report: 6th
Section of draft R7RS: 7.1.1. Lexical structure
Change syntax of [escaped] symbols from |<symbol element>*| to #"<string element>*"
The vertical line character is being proposed as a syntax for literal symbols. This symbol however is used by SCSH to represent shell-style pipes. The backslash is also being used for the same purpose (which is currently used by Gambit for infix notation). Also the <symbol element> and <string element> production are practically identical only differing because of the quote symbol used.
This proposal will allow freeing the | and \ characters for future use and eliminate <symbol element> production from the syntax.
