What use case do you have in mind which would > make this necessary? What's wrong with the case you use in that blog post? But as it turns out, I'm implementing a fact-based modeling DSL, where it's sensible to have classes like "AgeInYears" being a subclass of an integer like class. The formalism for this comes directly from sorted first-order logic, which makes a good deal more sense than the broken O-O paradigm discussed elsewhere in this thread. I suspect that you "doubt it is a good idea" only because Ruby's object model for numbers is inconsistent, and you're defensive about that. Not because Ruby 2.0 shouldn't move in the direction of fixing it, where possible. (BTW, I tried to join Ruby Core to discuss this, but all possible means of subscription are silently failing me). Note that I'm not actually subclassing any core integer class. I'm just defining a new base class "Int" which contains an integer, and so far as is possible, acts like one, including being found in a Hash using a Fixnum/Bignum key. If Fixnum and Bignum can act like Integer subclasses, why can't my class? >> In particular, the Hash implementations work (and break!) differently in >> MRI, Rubinius and JRuby. It's documented to use only #hash and #eql?, >> but that's not always true (sometimes these have hard-wired optimsations). > When you violate contracts you cannot expect code to work properly. I have not violated that (unstated!) contract. Read again; I redefine Fixnum#eql? as self.orig_eql?(i.to_i) - the to_i makes it symmetrical. (Debate the wisdom if you wish, it's just for demonstration purposes.) However the Ruby interpreters do not honor that. In short, *all three* mentioned Ruby interpreters violate the Hash contract, which states that hash and eql? are used for Hash lookups. Not just sometimes, but all the time, including for integers. MRI uses a Fixnum as its own hash value, even if you've monkey-patched a hash method into Fixnum. This optimisation should not be always-on. Instead, Ruby should detect when Fixnum has been patched, and bypass the optimisation. That would require a single test and branch, with insignificant impact on performance. MRI does however use a monkey-patched Fixnum#eql? method. Rubinius does the opposite. It calls a patched Fixnum#hash, but not Fixnum#eql? JRuby calls neither. The Ruby interpreters should behave the way the Hash documentation says they do. The Ruby documentation should explicitly state that eql? must be defined symmetrically, or should require that the Hash implementation uses it only in a known direction or both. >> The Hash documentation does not say whether #eql? will be called only on >> items in the hash, or only on keys being used to probe the hash.

Certainly not in TRPL, see sections 3.4.2 on page 68, and section 3.8.5.3 page 77. It makes sense, but it's not stated. > Having different > results for both violates the equivalence relation which means all > bets are off. No. I can fix the asymmetry. I can't make the interpreters honor that fix. >> You'll see that the behaviour is very unpredictable. > Yes, because of your violation of the contract. No. Because the Ruby interpreters don't honor the Hash contract. Please try to read more carefully. Clifford Heath.
