[Yhc] YHC.Primitive;_E

[Tom Hawkins]

To get the hang of using Yhc.Core, I'm writing a little haskell
interpreter.  The interpreter errors out when ever it comes across an
unknown primitive.  The first such primitive I had to implement was
SEQ.  Now I'm on to YHC.Primitive;_E.

What is the meaning of this type?  Is there a place where these
primitive types are defined?  When I print the coreDatas I see:

data YHC.Primitive;_E b =
      YHC.Primitive;_E b

When I print coreFuncs, I see no Case expressions that could extract
data put into _E.

Thanks for any tips!
