+Creates and initialises a new lexer/parser state object, supplying
+a context in which to lex and parse from a new source of Perl code.
+A pointer to the new state object is placed in L</PL_parser>. An entry
+is made on the save stack so that upon unwinding the new state object
+will be destroyed and the former value of L</PL_parser> will be restored.
+Nothing else need be done to clean up the parsing context.
+
+The code to be parsed comes from I<line> and I<rsfp>. I<line>, if
+non-null, provides a string (in SV form) containing code to be parsed.
+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, and must always
+be zero.

+down to the comma operator. The expression must be followed (and thus
+terminated) either by a low-precedence logic operator such as C<or> or by

+If I<flags> includes C<PARSE_OPTIONAL> then the expression is optional,

+dynamic parser state (L</PL_parser> et al) is correctly set to reflect

+expression.
+
+The op tree representing the expression is returned. If an optional
+expression is absent, a null pointer is returned, otherwise the pointer
+will be non-null.
+
+If an error occurs in parsing or compilation, in most cases a valid op
+tree is returned anyway. The error is reflected in the parser state,
+normally resulting in a single exception at the top level of parsing
+which covers all the compilation errors that occurred. Some compilation
+errors, however, will throw an exception immediately.
