Added InternTable
I was unable to use the macro for trait impls since it does not support lifetimes.
This commit looks like it lacks documentation and tests. Both are needed for me to accept the pull request.
I think that I can see the goal, which is to enable arena allocated interned pointers. I think in this case you should be able to implement it without unsafe, though.
Yep, that's fair. I'll try to find some time to push this to completion over the next week.
I've finally gotten around to taking a look at this, and it looks interesting. When I look at it, however, it seems like the borrow checker would prevent you from interning more than one object in a table, since the lifetime of the first entry would make the compiler think a borrow of the table is ongoing.
I haven't tested this, but it's worth putting in an example or test to demonstrate that it's not a problem.
