@item RETURN_INIT
If the function uses the G++ ``named return value'' extension, meaning
that the function has been defined like:
@smallexample
S f(int) return s @{@dots{}@}
@end smallexample
then there will be a @code{RETURN_INIT}. There is never a named
returned value for a constructor. The first argument to the
@code{RETURN_INIT} is the name of the object returned; the second
argument is the initializer for the object. The object is initialized
when the @code{RETURN_INIT} is encountered. The object referred to is
the actual object returned; this extension is a manual way of doing the
``return-value optimization''. Therefore, the object must actually be
constructed in the place where the object will be returned.
