  1. Currently we don't build cabal-setup committed Sep 19, 2006
  2. Packages cleanup, and allow new packages to be loaded with :set again

    This cleans up the package subsystem a little.  There are some
    changes to the GHC API as a result.
      - GHC.init and GHC.initFromArgs are no longer necessary.
      - GHC.newSession takes the root of the GHC tree as an argument
        (previously passed to GHC.init).
      - You *must* do GHC.setSessionDynFlags after GHC.newSession,
        this is what loads the package database.
      - Several global vars removed from SysTools
      - The :set command in GHCi can now cause new packages to be loaded,
        or can hide/ignore existing packages.

  4. Fix a bug in subsumption, and tweak error messages

    This commit does two largely-unrelated things, but they hit the same code.
    First, I tweaked the error messages a bit, to give better errors
    for impredicative polymorphism.  This added the mb_fun argument to
    Second, I fixed a long-standing bug in tc_sub.  In the isBoxyTyVar case 
    of tc_sub (rule F2) I was not recursing to tc_sub as the rule suggests,
    but rather calling u_tys.  This is plain wrong, because the first
    arugment might have more foralls.   
    The solution is to recurse to tc_sub, but that in turn requires a parameter,
    exp_ib, which says when we are inside a box.
    Test is tc210. committed Sep 18, 2006

  6. Ensure that only zonked poly_ids are passed to tcSpecPrag

    This is a long-standing bug really (Trac #900).  The poly_id passed
    to tcSpecPrag should be zonked, else it calls tcSubExp with a non-zonked
    type; but that contradicts the latter's invariant.
    I ended up doing a bit of refactoring too.  The extra lines are 
    comments I think; the code line count is reduced.

  2. Simplify desugaring of left sections

    	MERGE TO 6.6 branch!
    Some while ago I made the type checker a tiny bit more lenient about
    left sections, so that 
    	(x !)
    would typecheck iff
    	((!) x) 
    Strictly, Haskell 98 requires that the section typechecks iff
    	(\y. (!) x y)
    typechecks, and I should really have made the relaxation dependent on a 
    flag, but I didn't.
    Anyway, this commit fixes the *desugarer* so that it correctly desugars
    the programs that the typechecker passes. committed Sep 11, 2006
