sorry,

I want to maintain the const-ness of MyObj, and have read
access to the std::vector within std::map...

Then operator[] isn't the function you want. Something like:

std::map< std::string, std::vector< std::string >

::const_iterator

entry = obj.l_[ "key"=

] ;

const_iterator entry = obj.find("key");

Yes, obviously.

    if ( entry != obj.l_.end() ) {
        std::vector< std::string > const&
                            regexList = e=

ntry->second ;

// ...
}
