Perhaps I don&#39;t quite get how this works, but when I :set -fbreak-on-exception in GHCi, I get an exception using readFile. It reads the entire file and then throws what appears to be an EOF exception.<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">

This happens with both 6.10.1 and 6.8.3, so perhaps this is standard stuff, and I&#39;m missing something.<br>
