-------------------------------
	Fix a grevious bug in DsMeta
	which caused a seg fault
	-------------------------------

The bug was an incorrectly declared type for one of the Template
Haskell construction functions in DsMeta (repRecCon, repRecUpd)
and some associated jiggery pokery.

-dcore-lint showed it up nicely, because the desugarer generated
ill-typed code.
