I was handed 'ttlcache' on github and would welcome a review or tips on further testing

<p>I was handed over a repository on github, <a href="https://github.com/ReneKroon/ttlcache" rel="nofollow">https://github.com/ReneKroon/ttlcache</a> having a ttlcache in which i fixed multiple bugs as i was running into them in app i am now maintaining at work. Im mainly interested in better or different test cases. I identified that the benchmarks are only single threaded for example, but am looking for more tips to improve.

Checkign with %T is slower, and also would break in a confusing way if the code was refactored. (If the code was refactored, a type assertion would likely immediately not compile, because the type would not exist anymore.)</p> <p>-jeff</p></pre>RwKroon: <pre><p>I will fix it.</p></pre>
