Defined in GHC.Core.TyCon.RecWalk Methods ppr :: RecTcChecker -> SDoc # | |

The default upper bound (100) for the number of times a RecTcChecker is
allowed to encounter each TyCon.
setRecTcMaxBound :: Int -> RecTcChecker -> RecTcChecker #
Change the upper bound for the number of times a RecTcChecker is allowed
to encounter each TyCon.
