Hi Stathis,
With the code below you can query transitive relationships between
entities successfully. Is there any way to use core.logic explain
the relationship? Specifically, is there any way to write a function
explain so that:

Hello David,
Yes, I wasn't expecting for this to be built-in. Your example is exactly
what I was looking for, thanks a lot! I'll to need to spend some time to
figure it out :-)

There is no general explain functionality.
Thanks for this. I didn't think about that!

I'm not sure what you mean by this. Transitivity means that for all x,
y, and z, (Fxy Fyz) = Fxz. But there are values of x, y, and z for
which that does not hold.
Yeah, sorry. What I meant was that == is only commutative if you

When passing two arguments to ==, == will be transitive.
user [(== 0 0.0 0.0M) (== 0 0.0M 0.0) (== 0.0 0 0.0M) (== 0.0 0.0M 0)

I was bitten by this a year ago and posted here:
http://groups.google.com/group/clojure/browse_frm/thread/9091ad790fc96b24
My workaround is to call BigDecimal#stripTrailingZeros before passing
it to code that might compare it to some other number.
user (== 1 (.stripTrailingZeros 1.0M))
true

The only reason for this that I can think of is incomplete rules for
casting numbers.
