Hello,<br><br>     I am currently using ghc 6.8.2. With the following,<br><br>swishParse :: String -&gt; String -&gt; SwishStateIO (Maybe RDFGraph)<br>swishParse fnam inp =<br>    do  { fmt &lt;- gets $ format<br>        ; case fmt of<br>
            N3        -&gt; swishParseN3 fnam inp<br>            otherwise -&gt;<br>                do  { swishError (&quot;Unsupported file format: &quot;++(show fmt)) 4<br>                    ; return Nothing<br>                    }<br>
        }<br><br>I am receiving a shadow warning:<br><br>Swish/HaskellRDF/SwishCommands.hs:304:12:<br>    Warning: Defined but not used: `otherwise&#39;<br><br>It seems to me that in the code base somewhere that there is a &quot;redefine&quot; of the keyword&quot;otherwise&quot;. I haven&#39;t read the Haskell 98 Report but I thought that it was not possible to redefine keywords. ??<br>
