[boost] Re: [multi_index] composite keys: request for advice

[reformatted]

// yields true composite_key</* as before*> ck; ck(record(1,2,3))<=make_tuple(1,2);

// yields true make_tuple(1,2)<=ck(record(1,2,3));

So far, this is all IMHO perfectly consistent, but the following design decision is not obvious to me: given the previous, what should be the result of

ck(record(1,2,3))==make_tuple(1,2); // true or false?

As these two objects are neither greater than the other, at least they are *equivalent*, but maybe allowing operator== to return true is too much.

operator== should return false here. The operands are equivalent, but not equal. Dave
