Hi @DaanHoogland, this was only my first doubt (question). After that,
@mike-tutkowski and I exchanged some other messages and then I understood the
method. I see why a boolean return would not suffice all of its needs.
I was misled by the name of the method. Every time I see a method name that
starts with "can/has/is", I think that it will return a boolean value.
The code of this PR is OK for me; I would only suggest a name change on
that "canHandle" method to a more descriptive one.
