I am trying to learn Meta Haskell. One thing I want to do is create an identity function. It should get a type constructor as input and return the same type constructor as output. It should be possible to do:

$(idDecl data Foo = Foo Int)

and it should "return":

data Foo = Foo Int

Is this possible? if yes, how does one do it?

You mean: $(id [d| data Foo = Foo Int |]) ? Best regards Tomasz
