lispdoc - results for with-input-from-sequence

 (var sequence &key start end transformer) &body body)
Function: Creates an IN-MEMORY input stream from SEQUENCE using the parameters START and END, binds VAR to this stream and then executes the code in BODY. A function TRANSFORMER may optionally be specified to transform the returned octets. The stream is automatically closed on exit from WITH-INPUT-FROM-SEQUENCE, no matter whether the exit is normal or abnormal. The return value of this macro is the return value of BODY.
