	basic_regex&  assign(  const std::basic_string<CharT,ST,SA>& str,    (5)
     (since C++11)

			     flag_type f =
	std::regex_constants::ECMAScript );
	template< class InputIt >

	basic_regex& assign( InputIt first, InputIt  last,		     (6)
     (since C++11)

			     flag_type f =
	std::regex_constants::ECMAScript );
	basic_regex& assign( std::initializer_list<CharT> ilist,

     (since C++11)
	std::regex_constants::ECMAScript );

	Assigns the contents to the regular expression.

	1) Assigns the contents of other. flags() and mark_count()  are  equiva-
     lent to the
	values of other.flags() and other.mark_count() after the call.
	2)  Assigns  the  contents  of	other  using move semantics. flags() and
     mark_count() are
	equivalent to the values of other.flags() and other.mark_count()  before
     the
	assignment. After the call, other is in a valid, but unspecified state.
	3-7)  Assigns  a  sequence  of characters to the regular expression. The
     syntax flags
	are set to f. mark_count() returns the number of  marked  subexpressions
     within the
	resulting subexpression after the call.
	3) Assigns a null-terminated string pointed to by s.
	4) Assigns a sequence of count characters, pointed to by s.
	5) Assigns the string str.
	6) Assigns the characters in the range [first, last).
	7) Assigns the characters in the initializer list ilist.

Parameters
	other	    - another regular expression to assign
	s	    - pointer to a character sequence to assign
	str	    - string to assign
	first, last - the range of characters to assign
	ilist	    - initializer list containing characters to assign

Type requirements
	-
	InputIt must meet the requirements of LegacyInputIterator.

Return value
	*this

Exceptions
	1) May throw implementation-defined exceptions.
	3-7)  std::regex_error	if the supplied regular expression is not valid.
     The object is
	not modified in that case.
