Exactly. By design.
For classes, we have agreed on class-private, rather than
instance-private, instance variables. However you don't need such a
complex desugaring for classes, and "private x;" not in a class should
be evaluated, not hoisted into singleton-hood somehow.
class Point { ... private x, y; ... } // ignore details of whether in
constructor or class body
should desugar roughly to
let Point = do { private x, y; class Point { ... ... } };
so as to achieve the class-private instance variable semantics wanted.
This does suggest that putting the private declarations in constructor
is a mistake, since they would seem to be generated once per
construction (instance), not once per class (as class-private wants).
