Apparently, duplicate keys in sets are only disallowed in set
literals. Arguably, that must be a mistake on the users part, but
it sure seems to clash with the behavior of sets elsewhere.
Why would you ever want to write a duplicate in a set literal?

I think there are two important considerations in favor of how it works now:
(1) The common case presumptions (which admittedly may need to be learned).
(2) The need for both flavors. If there wasn't a flavor that rejected duplicate
keys, somebody would surely ask for it.
Add to these

For web development, my favourite tool is Django. It comes as a fullstack

My sense from reading Rich's writing on the subject is that 'contains?

involved whereby if 'contains? returns true, the the value returned by
'get is valid (this covers cases in maps where the value actually is

Following up, point (2) in my previous message would be helpful only if =

floats and doubles are inexact numbers and ratios, ints, longs,
bigints, and bigdecimals are exact numbers.
The expected behavior is that inexact things contaminate exact things,
because now the result is inexact. This is what Clojure does.
