#4234: GHC 6.13 doesn't support Haskell 2010's DoAndIfThenElse feature.
---------------------------------+------------------------------------------
Reporter: shelarcy | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler (Parser)
Version: 6.13 | Keywords:
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
GHC doesn't accept DoAndIfThenElse feature's sample code.
{{{
foo :: Monad m => Bool -> m Int
foo x = do
if x then
return 1
else
return 2
}}}
This code causes parse error.
{{{
Prelude> :load Test
[1 of 1] Compiling Main ( Test.hs, interpreted )
Test.hs:5:4: parse error (possibly incorrect indentation)
Failed, modules loaded: none.
}}}
Now, GHC support Haskell 2010 in HEAD ( #4098 ). So, GHC must accept above
program.
