CPP12 — Bug on _var references

he spec shows on page 1-13:

class A_var {
public:
// ...
operator const A_ptr&() const

// ...
};

The conversion operator is overloaded for const and non-const.

Now, two issues here:

1) It seems that "const A_ptr &" as the return type for the
first operator is wrong because it really means
"A * const", not "const A *". So, if anything, I think it
would have to be written as

operator const A * &() const

2) But why provide a const version of the conversion operator
at all? Object references are never passed with a const
qualifier, so why provide this conversion operator? I think
it could simply be deleted without affecting anything.

Proposal: Delete the const version of the conversion operator.

Opinions?
