-> is simply a code rewrite macro. You can use macroexpand-1 to see
how the rewrite is done:
user=> (macroexpand-1 '(-> {:a 1} (keyword "a")))
(keyword {:a 1} "a")
As Sunil said, you can get the desired behaviour by adding parentheses:
user=> (macroexpand-1 '(-> {:a 1} ((keyword "a"))))
((keyword "a") {:a 1})
In this simple case, a simple get would be sufficient:
user=> (get {:a 1} (keyword "a"))
1
...but I guess the code you posted was only the minimal case to
reproduce the error.
Sometimes, get-in can also be an alternative to ->.
