That does work sometimes.  But if the class is a template, or if the  
method is overloaded, I can't do it, or I have to type way too much,  
or I get this <incomplete type> error.   Examples...

(gdb) p set1.begin(&set1)
Cannot resolve method  
set<xml::XmlNode*,std::less<xml::XmlNode*>,std::allocator<xml::XmlNode*> 
  >::begin to any overloaded instance
(gdb) p set<xml::XmlNode*, std::less<xml::XmlNode*>,  
std::allocator<xml::XmlNode*> >::begin(&set1)
$1 = {
   _M_node = 0x3008c0
}

That works, but it's horrible.

(gdb) p set<xml::XmlNode*, std::less<xml::XmlNode*>,  
std::allocator<xml::XmlNode*> >::size(&set1)
$8 = <incomplete type>
(gdb) p (int)(set<xml::XmlNode*, std::less<xml::XmlNode*>,  
std::allocator<xml::XmlNode*> >::size(&set1))
Invalid cast.

I can't get the size(), bu it's similar to begin() -- both are  
inline, both return types that are typedef'd in the same place.


(gdb) p vector<xml::Step*, std::allocator<xml::Step*> >::begin(&steps)
non-unique member `begin' requires type instantiation

?
