I'm fairly new to C++, so forgive me if this question is malformed.

Is there a way, or should there be a way, to allow enumerations that have scope
only within their class?

For example:

class Boolean {
public:
  enum boolEnum { false, true };
  boolEnum value;
}

so then I could say

main() {
  Boolean bool;
  int foo;
  bool.value = true;
  foo = true;				// ILLEGAL - out of scope
}

currently I am declaring the enumeration to have global scope, which is
displeasing: it would allow foo to be assigned as mentioned.
