</div>System.IO.Error's try (and catch) is not the same as that of Control.Exception,<br>
because it only catches IOError's. catch is slightly more involved to<br>
change because its type is specified as catching only IOError, whereas<br>
Control.Exception.catch nearly always needs a manual annotation of the<br>
exception type.<br>
<br>
Replacing System.IO.Error.try with System.IO.Error.tryIOError should<br>
work, and is compatible with ghc's back to 7.2.<br>
