Subject: Module Syntax

Being primarily a C++ programmer, I'm happy with Ruby's Module concept
because it's pretty close to what I have with C++ namespaces, which I use a
lot (everything gets wrapped up in a namespace somewhere).  However, I'm
puzzled by some syntax I discovered by accident and I was wondering if
anyone could tell me what this is.

It was becoming tedious indenting everything like this:

module MyModule
    def MyFunction
        mycode()
    end
end

....so just for the heck of it, I wrote this:

def MyModule::MyFunction
    mycode()
end

....and it worked!

But...for all the reading I've done, I don't recall reading anything like
this.  Why does this work and what is it doing?  Has it attached itself to
the Module "MyModule?"
