#2529: deriving Read fails on infix data constructors with record syntax
-----------------------+----------------------------------------------------
Reporter: spl | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.8.3 | Severity: normal
Keywords: | Testcase:
Architecture: x86 | Os: MacOS X
-----------------------+----------------------------------------------------
The example below successfully performs the {{{show}}}, but {{{reads}}}
returns an empty list. It fails in both GHCi and GHC. It succeeds if you
replaces the infix symbol with a name.
{{{
module Main where
data A = (:<>:) { x :: Int, y :: Int } deriving (Read, Show)
t :: A
t = 1 :<>: 2
s :: String
s = show t
r :: [(A,String)]
r = reads s
main :: IO ()
main = do putStrLn s
putStrLn (show r)
}}}
