How to convert this list into map?
Hi,
I have this list:
(:= :language Clojure)
And I want to convert it to the following map data structure:
{:op := , :language Clojure}
I can't really think of a clear way how to do it.
Would you please help?
Thanks for help and time.

user= (apply hash-map (conj '(:= :language Clojure) :op))
{:op :=, :language Clojure}

Re: How to convert this list into map?
Here is how you can derive that expression:
{:op :=, :language Clojure}
is the same as
(hash-map :op := :language Clojure)
which is the same as
(apply hash-map '(:op := :language Clojure))
So, all you need is
'(:op := :language Clojure)
which can be produced by prepending :op to your original list
(conj '(:= :language Clojure) :op)

Re: How to convert this list into map?
As a slight simplification you can take advantage of the fact that apply
handles in-line arguments as well as a seq of arguments at the end. This also
works:
user= (apply hash-map :op '(:= :language Clojure))
{:op :=, :language Clojure}
