So, I googled for this, and it looked to me like just a BTree implementation --
 not a use case.  But since you didn't tell me what the use case was, I may 
not have googled for the right thing...

Note that I'm not asking if they *allow* a user to store incompatible types.  
I'm asking for a case when a user *wants* to store incompatible types.
