Hi Mingli, (2) How can we express something like a type with parameter and the > initialization of a type with parameter. >
I'm not an expert, so don't take my word for it. But let me guess. Haskell is based on simple type theory while set.mm is ZFC, i.e. set theory. They are different beasts. You can embed type theory, of course, but that would not be set.mm anymore, IMHO. But maybe some real expert will say that I'm telling nonsensicality and this should be easy to do :) -- You received this message because you are subscribed to the Google Groups "Metamath" group.
