Refactoring of the way that inlinings and rules are activated Principally, the SimplifierMode now carries several (currently four) flags in *all* phases, not just the "Gentle" phase. This makes things simpler and more uniform. As usual I did more refactoring than I had intended. This stuff should go into 7.0.2 in due course, once we've checked it solves the DPH performance problems.

Add warning for probable identities (fromIntegral and friends) See Trac #4488. The basic idea is to check for fun :: ty -> ty where fun is one of toIntegerName toRationalName fromIntegralName realToFracName There's a (documented) flag to control it -fwarn-identities. Currently -Wall switches it on.

A (final) re-engineering of the new typechecker Regression testing and user feedback for GHC 7.0 taught us a lot. This patch fixes numerous small bugs, and some major ones (eg Trac #4484, #4492), and improves type error messages. The main changes are: * Entirely remove the "skolem equivalance class" stuff; a very useful simplification * Instead, when flattening "wanted" constraints we generate unification variables (not flatten-skolems) for the flattened type function application * We then need a fixup pass at the end, TcSimplify.solveCTyFunEqs, which resolves any residual equalities of form F xi ~ alpha * When we come across a definite failure (e.g. Int ~ [a]), we now defer reporting the error until the end, in case we learn more about 'a'. That is particularly important for occurs-check errors. These are called "frozen" type errors. * Other improvements in error message generation. * Better tracing messages

multiline commands in GHCi #4316 This patch adds support for multiline commands in GHCi. The first line of input is lexed.

Multiline mode is toggled with `:set +m`
