    I have some class "foo":
class foo {...};

And I have some function bar:
void bar(const foo& foo2)
{
 foo2.member();
}

    This generates a "warning: passing `const foo' as `this' argument of `void
foo::member()' discards const".
Does this mean that I can't call any member functions of a class which is
passed as a const-reference without risking modification of the class data?  I
could just remove the 'const', but I did it to prevent other warning messages
like if I were to call "bar((foo)5)".
