This one is not a good example: it takes a parameter. You cannot
convert it to a property.

When designing an API, when I have to choose between property and
function/method, I prefer function/method over a property when the
code is slow, especially at the first call.

I prefer to "warn" users than a call (like the first one which fills a
cache) can be slow.

Well, it's not a strong rule, sometimes I use a property even if the
first call has to fill a cache :-)

Here the sysconfig has to build an internal cache at the first call
... if I recall correctly.
