[fpc-pascal] Classes and class methods

[Mark Morgan Lloyd]

Is it possible to put a class (not an instance) in a variable or array 
element, and to use this to call a class method?

I'm defining a hierarchy of classes and it would be convenient if it 
were possible to register the fact that a class had a particular 
subclass, such that the information was available before instantiation.

I'm assuming that the code that inspects the array has imported all 
units so is aware of the relevant class declarations, but I am still 
having problems with calling class methods and/or casting to a class (as 
distinct from an instance).
