You can overload operators for enums, so I often overload operator<< and operator>>. Something like this:

I have a Python script somewhere that generates the above code given a list of enum names but I can't find it.

std::string EnumToString( Key& k ){	std::stringstream str;	str << k;	return k.str();}

Good idea. But wouldnt I then be forced to do a second function to get the actual string rather than a stream? Streams arent all that ideal to work with if you want to compare strings.

And how fast is this? Allocating and deallocating streamobjects, the switch statement.

  std::ifstream f("config.txt");  while (...) {    Keys key;    Actions action;    f >> key;    f >> action;        // bind the key/action pair in your application  }

You're missing error handling, either Unknown enum value, or exception being thrown.

As it is, the >> operator can return undefined value, and << can do a nop, which would corrupt the file.
