That's where you're mistaken. char, signed char and unsigned char are 3 distinct types.

Hi Eric. After learning about int "abcd" literals from your mpl::string post, I'm now learning about an integral type which is neither signed nor unsigned!

(sounds like my assumption that char is an integral type might be wrong in fact...)

Would you mind expanding a little on this, possibly with pointers to further info please?

My naive take on char was it was either equivalent to signed char or unsigned char in a platform-specific manner, but if it's boost::is_same to neither, I'm confused...

char is always equivalent to either signed char or unsigned char, but it is not the same type. It is always a distinct type. In Christ, Steven Watanabe
