Indeed, it seems tricky to get that working! I am not sure I will be 
able to find the time to look deeper into this. At a first glance, I 
would try to wrap function IDs into a new Val type that is able to carry 
the context. The particular context would be determined, when evaluating 
the expression, which returns the anonymous function. In the end, when 
the function is called, the context values could be treated as 
additional arguments.
