I'm trying to use RoelTyper in Pharo. A question I ask myself is: 'Is it normal that roelTyper doesn't always return some assignements' ?

For example, when I evaluate:

��TypeCollector typeInstvar: #array ofClass: OrderedCollection .

the assignements returned is an empty collection. I would expect that even roelTyper doesn't retrieve the exact type, it would always return a collection of 'candidate' types.

Am I using it in a wrong way?
