Delphi Prism Member Modifiers
by Mike Prestwood

Prism supports a full suite of member modifiers. Prism virtuality modifiers are virtual, override, final, and reintroduce. Prism general modifiers are abstract, empty, async, external, locked, unsafe, implements, and iterator. Not all member types support all member modifiers. For example, member fields support only readonly and implements.
