Cheaper and simpler than talking to lawyers would be simply to write a new
compatible one.  On the way it could export an API so that other objects
could evaluate expressions (you could embed them in messages, make a Max-like
'if', maybe have a thing that creates objects with expr-calculated creation
arguments, etc).
