class_docstr: This class abstracts handling of a set of version specifiers.
  
  It can be passed a single specifier (``>=3.0``), a comma-separated list of
  specifiers (``>=3.0,!=3.1``), or no specifier at all.
docstr: Return a SpecifierSet which is a combination of the two sets.
  
  :param other: The other object to combine with.
