Move Record desugaring to constrintern and add ability to use notations
for record fields (using "someproj : sometype where not := constr" syntax). Only one notation allowed currently and no redeclaration after the record declaration either (will be done for typeclasses). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11542 85f007b7-540e-0410-9357-904b9bb8a0f7
