Agreed, however, that's not an argument against or in favor of either
solution.

Write-only properties are quite rare, just don't use chained assignments
in these cases.

It's only confusing for non well-behaving properties. The right solution
is to fix the property.

One reason why I don't like Semantic B is that sensible memory
management wouldn't be possible in that case for non reference-counted
objects.
