* chore: Abuse deftemplate to get rid of Address * chore: Avoid semicolon at end of define * fix: address should be useable as an argument to a HOF * chore: adapt examples to new address signature * fix: Remove Address from typeOf * fix: Remove more uses of Address * fix: Remove more mentions of address in the Haskell code * fix: Remove test that ensure you can't take the address of non-symbols * refactor: Moved `address` to Pointer.carp * refactor: Move address into Pointer module Co-authored-by: Jorge Acereda <jacereda@gmail.com>
