A class is abstract by design and not necessarily because I can compute something from its implementation that tells me that maybe it is abstract.
I somehow mark a class as abstract because it is abstract, not the other way around.

Randon idea...

``#Frame abstract`` returning a hypothetical instance of��AbstractClassSymbol

which double-dispatches to set a property of the class when it is created

per...

��Object subclass: #Frame abstract

instanceVariableNames: 'frameNumber frameRolls nextFrame'

classVariableNames: ''

package: 'Exercism-Bowling'
