v52 v53 101 101 The `haskell98`, `old-time`, `old-locale` and `random` packages are mostly only needed for Haskell 98 support, although `dph` currently uses `random` too. 102 102 103 == WARNING: Pattern matching in `ghc-prim`, `integer-simpl `, and `integer-gmp` == 103 == WARNING: Pattern matching in `ghc-prim`, `integer-simpl`, and `integer-gmp` == 104 104 105 105 Note that `ghc-prim` and `integer-impl` are below the dependency chain from Exception (in `base`), which means they must not raise generate code to raise an exception (it's not enough that this code will never run). One particularly subtle case of GHC exception-raising code is in the case of (complete!) pattern matches. Consider the unboxed form of Integers, which has the constructor S# or J#.
