Yeah, upon further reverse engineering, the way string hashing "works" is that it simply adds up all the character code values of the characters and returns this sum. The implementation is in dmd\src\druntime\src\compiler\dmd\typeinfo\ti_AC.d , and I've verified this both by reading the code and by implementing the same thing myself and seeing if the results are the same. If anyone has a better way to do it (which would be almost anything; I've written a few myself, although they are extremely simplistic and I'm sure anyone who actually knows what they're doing could do even better), please submit a patch. I've filed this as bug 2922, because it's a severe performance issue, so please submit there.
