Answering my own question, one can achieve the goal via doing a lookup, if the number of possible parameters is limited.
eg. assume add is a function which can only take Int's from [0..9].
Interestingly, my situation is exactly like this. I think I'll implement such a lookup.
The question is still open though, if somebody has some magic to extract the prameter from an applied function...
You can't, because it's a chunk of machine code, not an AST that can be walked to pull out parameters. The solution is to convert it to the latter form (in the simplest case, a tuple is good enough; if you need something more complicated you'll have to define an actual AST datatype).
