<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">A lot more wibbles
* Made String wired-in, so that
"foo" :: String rather than
"foo" :: [Char]
* isTauTy: account for =>
* Bring dicts into scope when desugaring HsWrappers:
addTyCsDs and hsWrapDictBinders
* Improve reporting for occurs checks where
skolems are involved e.g. 10715b, mc19, tcfail193, T13674,
T4272, T3169, T7758, 7148
Payload is in the first case of mkTyVarEqErr
* solveLocalEqualitesX: fail faster.
we want to fail fast in T11142
Another example: T15629
And keep all equalities in dropMisleading. This gives better
reporting in T12593 for example.
* Move checkDataKindSig after the solveEqualities and zonk,
obviously!
* Move ic_telescope into ForAllSkol; a nice win.
* Pretty-printing AbsBinds
We are now very close to green
