I know this goes against your talk at DConf, but having to write 
string parameters does not feel good. I'm will properly not be 
the only one who will mistype "apend" and wonder why the other 
template function will be chosen. I rather have the compiler 
scream at me telling me there is no symbol hasApend. And 
hasAppend!Container is less typing than hasMethod!(Container, 
"append").
