I don't know what kinds of objects you expect to work with booleans, but I
think you misunderstand the technical meaning of 'open' and 'closed'.

By 'closed', Marc means *solid* meshes, because any other ('open') kind
of mesh is impossible and doesn't exist in reality.

Can you give an example on what kind of object you would like to do
booleans with, and you would consider 'open'?

An example of a mesh that wouldn't work with booleans is half an
UVsphere. It would not work because it has no inside and no outside, and
is infinitely thin. Such an object wouldn't work with raytracing, either.

So, construct sane objects, and enjoy booleans, and don't blame the code,
I'd say ;-)
