Hrm. Sounds like getting the hash of an infinite sequence will hang or
cause OOME.
On the one hand, *most* uses of the hash are followed by .equals if the
hashes match, and .equals on an infinite seq can't work, since if it gives
up and says equal after some large number N of elements, the seqs

Eh. Not just any collisions, but only ones where the succession of tails
are equal-as-seqs but not identical as objects (.equals, but not ==) for
sufficiently long. So seqs that differ after only a trillion items would
blow up. So would equal ones sharing no tail structure. Putting (iterate

keyset-b looks up itself (because collections are functions) for the item

#(keyset-b #(.getID %))
And now let's assume that item-object is passed to it. So, #(.getID %)
returns,

The question should probably be asked: is there a benefit in a given
situation to having the let be outside the scope of the defn? I would argue
that most times it is not, and putting the let outside the function
clutters the code and makes it harder to see the functions defined in the
namespace.
This seems to be a recurring issue. I don't see a public list/bug tracker
for clojure.tools.logging, so I'm not clear on where I'm supposed to bring

Hi Clojurians,
I'm relatively new to the language and am trying to get used to its idioms.
One thing I'm accustomed to doing in things like java and C# is checking
values for validity and then bailing out early if they don't make sense.
For example, without this idiom in java you might do:

- pull sexp up to let, or introduce a new let (like introduce variable in
