title: Are the words Element and Sequence reserved in Swift?
body: <p>In my (chemistry related) project, I'd like to use the words <code>Element</code>and <code>Sequence</code> for data structures. Will there be a conflict with the same names that are already used in Swift, should I rename them to <code>MyElement</code> and <code>MySequence</code> to be safe?</p>
  
  <p><strong>UPDATE:</strong>
  I'm editing the question to hopefully make it more clear as was requested.  The following quote is from the Generics section of Apple's Swift documentation:</p>
  
  <blockquote>
    <p>Element defines a placeholder name for “some type Element” to be
    provided later on. This future type can be referred to as “Element”
    anywhere within the structure’s definition. In this case, Element is
    used as a placeholder in three places</p>
  </blockquote>
  
  <p>So, my question was if I can use the word <code>Element</code> for a structure without conflicting. The same for <code>Sequence</code> which I have seen used as well in sample code - although I cannot find it anymore.  The accepted answer below explains this.</p>
