(update n f & args)

Updates a Var identified in a namespace with a fully qualified identifier n, using a function f. The function will receive current value of the Var and any optional arguments passed, and its returned value will be used to alter the root binding. If the Var does not exist, it will be created and the function f will receive nil as its first argument. Returns a value returned by calling f.
