def __new__(cls, handle, **kwargs):
assert type(handle) is SortedSetHandle<EOL>if len(kwargs):<EOL><INDENT>r = handle.zfind(**kwargs)<EOL><DEDENT>else:<EOL><INDENT>r = handle.zrange()<EOL><DEDENT>return tuple.__new__(cls, r)<EOL>
This calls zfind or zrange on handle.
            Notice that other query-constuctor methods exist.
