Isn't the docstring a bit tautological?  Does property mean the same in
the beginning and the end of the sentence?  Sorry if I’m missing something
obvious here...

The first occurence "binds" the parameter name within the semantic
structure of the sentence, so to speak, whereas the second one provides
the description of what is done to the obtained entity.

Coming from the Common Lisp background, the uppercased argument names
are often used for this kind of semantic "binding", and in these cases
the need to explain what is done to the "bound" names isn't obviated.

It's merely a cultural default, so I have no particularly strong feeling
about the docstring.

If you have a better idea, we can discuss that : -)
