Thanks, fixed.

In the TypeScript translation of the kata, running the kata fails because of the first two lines in the sample tests (the reference directives). However, if I replace

	/// <reference path="/runner/typings/mocha/index.d.ts" ></reference>
	/// <reference path="/runner/typings/chai/index.d.ts" ></reference>

with the following:

	/// <reference path="/runner/typings/mocha/index.d.ts" />
	/// <reference path="/runner/typings/chai/index.d.ts" />

it works as intended. Not sure if this only fails for me, but this fix should work.

You're welcome! :]

Yes, you're right. I thought the debug output looked strange. I should have used concat instead, thanks!

You do realise that Array + Array casts both of 'em to Strings, don't you? And String also happens to have indexOf, and V0 just happens to come before V0+ ..

You'd have a most interesting bug when V0- is introduced before V0.

I believe this is actually an issue with the test cases themselves, as some people have pointed out already.
The test case in question uses the parameters [1, 7] and [1, 8], which should return 0 but the test case wrongly expects 1.

Hey! I've added a Clojure translation for this kata a while back. Would be great if someone could review it!
