Using a class means sending a class message to it, or using the class  
type as a first class entity in the program (e.g. "x is classtype"). A  
typecast can be handled completely at compile time (unless you compile  
with -CR, in which case above will be translated into "with  
(theclassinstance as ttheclass1) do begin" and hence the class type  
will becomes a first class entity; but you cannot do that anyway when  
using "class crackers" since the as-operation would throw an error).
