Re: How best to implement a hash table in Mathematica


Sorry, can't add more here. I myself learned about these functions very
recently from this post by Oleksandr Rasputinov:

And that's pretty much all publicly available information on this, I
believe. These functions probably serve internal purposes, and so are undocumented. This is a normal practice, anyone who is willing to dig out and use undocumented functionality should accept that it is, well, undocumented.
