--- Comment #1 from Yusuke Suzuki <utatane.tea at gmail.com> ---
I don't remember the exact bug number (maybe, in the context of Symbol and IdentifierRepHash), IIRC, when I attempt to change this to PtrHash, I heard the following reason why we did not use PtrHash; We intentionally use StringHasher instead of PtrHash because it gives nicer distribution for Strings and reduces collisions in the hash table.
So when changing this, I think measuring collision and performance is nice.
