I'm not seeing anything that appears to be missing from .String~instancemethods, so I'm not seeing
any problem here.
Oops, you are right, there was a coding error (corrected code below)!
There is certainly one error in your assumptions. You are assuming that any class object will
automatically have all of the methods of .Class, but other class objects do not directly inherit
from .Class, but are instances created by .Class (or rather the metaclass, which is .Class in
most cases).
Yes, indeed, metcalasses, would need to be taken into account for a general test (and if so, their
superclasses up to and including .class would need to be processed)!
That new class object does not automatically get all of the methods of the metaclass, for example,
the NEW methods.
This is an important information, as NEW is treated then as a special case at class object
construction time. Would that also mean that it is not possible to invoke "self~new:super"?
In that state, it is barely usable. The full scope of the instance methods is then built up by
adding in the inheritance hierarchy. So, if you are manually trying to construct things yourself,
you would do this by adding the instance methods from each superclass, ending with adding in
.Object~instancemethods(.Class).
Thank you for all of your explanations!
