Frequently when working in the repl I want to take a datastructure and
copy it into a test, however if that datastructure contains lists or
more often lazy-seqences these are printed within unquoted (), so when
I copy the result into my test I need to replace these lists with
vectors or quote them.
(pr-str {:a (range 0 3)}) => "{:a (0 1 2)}"
If I read the result as clojure code I would read it as call the
function 0 with the arguments 1 2 and save the result as the value
to :a in the map, which is not a correct interpretation of the
original datastructure.... unless that datastructure is actually code,
but most of the time it is not. Most of the time its a datastructure
that is printed at the repl during development...
I think it would be very useful to have a binding or alternative
method that should be used to print results at the repl which would
print datastructures in a form that correctly represents the code
necessary to create them, either "{:a [0 1 2]}" or "{:a '(0 1 2)}".
Personally, I think vectors would be a more idiomatic representation
of serialized list structure, but quoted list would at least be a
correct representation of the datastructure that one could easily copy
and paste into a test.
