What are the main purposes of using std::forward and which problems it solves?
...f we leave t1 & t2 as lvalue?
If, after instantiating, T1 is of type char, and T2 is of a class, you want to pass t1 per copy and t2 per const reference. Well, unless inner() takes them per non-const reference, that is, in which case you want to do so, too.

Fastest hash for non-cryptographic uses?
... Just a quick note - I tried this with a much longer string (~5000 chars) and CRC32 was slower than MD5 and SHA1 on my machine (i7-6650U, 16GB). CRC32 - 1.7s , MD5 - 1.4s, SHA1 - 1.5s. Always test for yourself.
