title: Naming convention for a function that analyzes several objects and returns a boolean value
body: <p>It is well accepted that assertion functions that check a single value/object have names that start with "is" (<code>is_valid</code>, <code>is_ok</code>, <code>is_empty</code>). I have a function that compares several objects (strings, in my case) and decides whether they are "similar enough". How would you name such a function? My variant is  <code>are_strings_similar(s1, s2, s3)</code>, but it looks somewhat awkward. </p>
  
  <p>The code is in Python, BTW</p>
