.. _release-9-2-1:
Version 9.2.1
==============
Compiler
~~~~~~~~
- New '-Wredundant-bang-patterns' flag that enables checks for "dead" bangs.
For instance, given this program: ::
f :: Bool -> Bool
f True = False
f !x = x
GHC would report that the bang on ``x`` is redundant and can be removed
since the argument was already forced in the first equation. For more
details see :ghc-flag:`-Wredundant-bang-patterns`
