Re: std::map with multi values

I had tried the std::pair<T,T>, but I can't compile it.
on
for(std::map<std::string, std::pair<T,T> >::iterator it =
m_initvalues.begin(); it != m_initvalues.end(); ++it)
(m_initvalues is declared std::map<std::string, std::pair<T,T> >
m_initvalues;) I get:

error: dependent-name 'std::map<std::basic_string<char,

parsed as a non-type, but instantiation yields a type
