Parsing

• read-case-sensitive: parameter for a Boolean value that controls parsing input symbols. When this parameter's value is #f, the reader always returns downcased symbols (e.g., hi when the input is any one of hi, Hi, HI, or hI).
• read-square-bracket-as-paren: parameter for a Boolean value that controls whether square brackets (``['' and ``]'') are treated as parentheses. See section 14.3 for more information.
• read-curly-brace-as-paren: parameter for a Boolean value that controls whether curly braces (``{'' and ``}'') are treated as parentheses. See section 14.3 for more information.
• read-accept-box: parameter for a Boolean value that controls parsing #& input. See section 14.3 for more information.
• read-accept-type-symbol: parameter for a Boolean value that controls parsing #<...> input. See section 14.3 for more information.
• read-accept-compiled: parameter for a Boolean value that controls parsing pre-compiled input. See section 14.3 for more information.
• read-accept-bar-quote: parameter for a Boolean value that controls parsing and printing a vertical bar ( ) in symbols. See section 14.3 and section 14.4 for more information.
• read-accept-graph: parameter for a Boolean value that controls parsing input S-expressions with sharing. See section 14.5 for more information.
