chapter 2 there is a statement -
The imperative indexOfAny must deal with several special cases:
null or empty strings, a null or empty set of search characters,
and the absence of a match. These special cases
Hi ka,
You're right. Eliminating special cases is more a factor of the design

combination with a functional programming language makes your code
extremely elegant. Thus
'when pred' just checks that you're not passing in garbage for the
predicate -- it's probably not really necessary and it might be better
to let Clojure throw an exception.
Totally agree on your point with the branching. That's not really FP-
related, it's only that most FP languages allow
