Not within the same file.

You can have an "interface file", extension .di, which hides the bodies 
of functions. But inside the implementation file, you must repeat the 
class/struct definition. So it's a lot of extra work. The compiler can 
spit out a .di file based on your implementation with the bodies hidden, 
but it's not perfect.

You also can't hide template function bodies.

What is your use case, or is it just that you prefer doing it that way?
