Description

We have indexOf(String, String), lastIndexOf(String, String) but no method to
pick of a specific n-th occurrence (I need the 2nd one for example). So I
propose to add (post 2.0):

nIndexOf(String, String, int).

I am not in love with the method name, but what else to call it? It does fit in
the pattern <occurrence>IndexOf() that the other methods have, where indexOf()
is really firstIndexOf(). Alternatives?:

nThIndexOf(String, String, int) - kinda weird
countIndexOf(String, String, int) - weirder
indexOfOccurrence(String, String, int) - a bit wordy but ok.
indexOfAt(String, String, int) - short; confusing?
indexOfStringAt(String, String, int) - we got rid of "String" in a bunch of
method names already, odd to reintroduce?
