On the one hand, *most* uses of the hash are followed by .equals if the

It stands to reason that transients won't help given a small number of
operations. Consider a simplified model where conversion to transient and,
eventually, back to persistent takes a constant number of cycles T and
every operation on a transient takes exactly d cycles less than the
corresponding
minutes with only the arithmetic left in the loop. Either something's
getting boxed or it's the trig calls.

Whuh? Double precision exponents should go up to 1023 and single

Replacing (range 10) with (take 10 (iterate inc 0)) didn't change

I need it to parallelize even for low-length sequences because the
individual elements may be expensive and there may be few of them.

I'd mostly be inclined to accept this quirk as odd and

that, according to the OP, serializing and deserializing an object

101?
Or maybe you meant (partial + 100). :)

Embarrassingly, it took this long for me to realize there's a much

Where the exception throw is for map literals with odd numbers of

Nevermind:

#'bar vs. (var bar);

Attract 0.7 more people per 1000 on average to adopt the language, perhaps. :)
On the contrary, discussing ideas relevant to Clojure is quite on topic here.
Once again: if *you* find this thread useless or uninteresting, *you*
can safely ignore it, but telling everyone else what to discuss and
what not to discuss (when they're not straying from the list's

In increasing order of difficulty...
Option 1:
Extend your comparator to sort first on the key you're actually
interested in, then if that key isn't different on the others
more-or-less arbitrarily.
Option 2:
Keep the data unsorted in a hash-set. Sort when you need sorted data,
e.g. for user pr

#{foo bar baz} is somewhat ugly. It occurs to me that one could modify
the reader to additionally accept
{{foo bar baz}}
without breaking anything. It's not possible for it to be a valid map
literal, because the outer {...} pair has only one object inside it
and a map literal requires an even num

Clarification: stop comparing to match the :id key against the target.
