You'll never really 'replace' any values so why not reduce/reduce-kv ?
Just build a new map out of the old one...

Hi all,
I think this is one of those questions which has quite a few answers,
but given a map, how do I replace the values by applying a function to
those values, but only if they meet a condition?
I understand the building blocks of (map..), (filter..), (assoc-in..)
and (filter..) and I can see how something could work using those
pieces but is would be pretty verbose. I am sure there is probably a
much more simple way using a more abstract function.
The actual use case is I have a list of maps as returned from the
clojure.java.jdbc framework and they contain timestamps. I want to
replace all the timestamps with (for example) to a Joda LocalDate
using the excellent clj-time library.
Any pointers?
Thanks!
