Yes, auto ref does the trick. I prefer it to passing the slice by 
value, because I can extend the function to cater for more types. 
My implementation (which is different from the one posted above) 
works also with strings, for example. Anyway, it gave me a 
performance boost of ~2.7 times as compared to the workarounds I 
had. This was well worth it!
