Re: List of commonly used property names when used as *inverse*?

My two cents:

Any mechanism for supporting inverse properties *at the level of syntax* are great. Reverse properties in the vocabulary are *evil* ;-) (well, undesirable).

While it may solve an initial pain point, what I am told it that it complicates code bases further along.  I dont know if this applies also to your aliasing use case, but I've been told in the past, to try to pick one direction and use that, it may be something to note.
