<p>
The overloads that accept a string refer to a named sub-expression <span class="emphasis"><em>n</em></span>.
In the event that there is no such named sub-expression then returns an empty
string.
</p>
<p>
The template overloads of this function, allow the string and/or character
type to be different from the character type of the underlying sequence and/or
regular expression: in this case the characters will be widened to the underlying
character type of the original regular expression. A compiler error will
occur if the argument passes a wider character type than the underlying sequence.
These overloads allow a normal narrow character C string literal to be used
as an argument, even when the underlying character type of the expression
being matched may be something more exotic such as a Unicode character type.
