What's wrong with this template definition?

Hi, I'm struggling with templates.

In a header file (.h), the following template is declared:

=====================
#include <map>
template <class T>
class symtblpp
{
private:
     typedef std::map< std::string, T > maptype;
     maptype _map;
public:
     T* lookup( const std::string& );
};
=====================

In the implemantation file (.cpp) the member function lookup is defined:
=======================
template <typename T>
T* symtblpp<T>::lookup( const std::string& key )
{
    maptype::iterator it = _map.find( key );

    return &(*it);
}
=======================

The compile (g++ 4.3.1) complains:

symtblpp.cpp:42: error: expected `;' before ?it?
symtblpp.cpp:45: error: ?it? was not declared in this scope

where line 42 refers to the line with the iterator.

Can somebody explain to me what's wrong?

Thanks in advance.

{ Short answer: use "typename" in front of maptype::iterator. -mod/sk }
