Re: [isabelle] Reference for Pure
Sorry, I'll try to clarify clarify my question. For example, if the
transformation is to negate each axiom in a theory or the
transformation is to make some syntactic changes, e.g., rename certain
term to something else, then is it still expressible in Pure? I've
just found http://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-130.pdf and
it seems that there isn't appropriate syntax at least for the latter.
If that's the case, does that mean these transformations would sit in
a separate meta-level in the logic hierarchy -- between Pure and the
Please let me know if more clarification is needed.
