Hi!

is there a (possibly boost powered) way of distinguishing between
const char* and const char[N]?

e.g.

const char* foo = "foo";
bar(foo);
bar("foo");

The second call to bar should extract the length at compile time, e.g.

template <size_t length> void bar(const char (&data)[length]) {...}

The problem is that in the presence of the first variant (void bar(const 
char*))
the second variant does not get called.
