I know, but it should. At least this is what your compilers
error message means in plain english:

> ttt.c:20: passing `const AAA' as `this' argument of `void AAA::foo1()'
> discards qualifiers

means

"You try to call a non-const function for a const object"

Oh sorry. Just figured out that the error message doesn't talk
about the operator altogether. Instead you somewhere try
to call a function fool(). But the cure is the same. Make
foo() a const member function.
