IL already works with dynamically typed languages to a degree (e.g. JScript, 
Mercury).

JScript in particular represents everything as an "Object", and then uses the 
"is" operator and the "GetType()" method to determine what something is 
before using it.  There are a bunch of conversion methods in the "Convert" 
class for converting arbitrary objects into specific types (Convert.ToString, 
Convert.ToNumber, etc).

I hope this helps.  Fergus may be able to provide some additional pointers 
from his Mercury experience.

Cheers,

Rhys.
