I just had a thought, I could check if dataName is in 
[__traits(allMembers ... )]. That would at least ensure I'm 
referencing something that exists. Maybe that'd be useful in 
vibes Bson/Json code. (Except the opposite, you want to check 
you're referencing something that DOESN'T exist, so you can be 
sure it's not 'remove' for example).
