title: Case sensitivity in Scheme symbols
body: <p>From what I have read, symbols in Scheme are case insensitive - i.e. <code>(eq? 'Hello 'hello)</code> evalulates to <code>#t</code> (because both are represented by the symbol <code>'hello</code>, and scheme has the property that two symbols with the same name are the same object). However, this doesn't seem to be the case for me, and things seem to be case-sensitive, whether I try using the <code>#lang scheme</code>, <code>#lang racket</code> or <code>#lang eopl</code> flavours of Scheme. Does anyone have any ideas why?</p>
