+A copy of the string is made, so subsequent modification of I<line>
+does not affect parsing. I<rsfp>, if non-null, provides an input stream
+from which code will be read to be parsed. If both are non-null, the
+code in I<line> comes first and must consist of complete lines of input,
+and I<rsfp> supplies the remainder of the source.
+
+The I<flags> parameter is reserved for future use. Currently it is only
