It's precisely the behaviour you would get by calling String.valueOf(null) in
java. Nulls match to the most specific parameter type in a given hierarchy,
and in this case, that would be char[] instead of Object. If the param
types were not in the same hierarchy, say char[] and String, then
Hi,
I discovered this testing some code this evening:
(String/valueOf nil) ; throws NullPointerException
(#(String/valueOf %) nil) ; null
Another formulation of the above (courtesy of brehaut in IRC):
(let [s nil] (String/valueOf s)) ; exception
(let [s nil] (String/valueOf ^Object s)) ; null
