Forgive me for jumping in without reading the whole thread (Webmail is a real PITA for this) but; No that is not completely correct. It does depend on what you are doing. In Delphi, the _usual_ way to assign a method pointer is as follows: type TMyMethodPointer = procedure (const s; string) of object; var mp: TMyMethodPointer; ... mp := AnInstance.CompatibleMethod; ... However, for function pointers: type TMyFuncPointer = procedure (const s; string); var fp: TMyFuncPointer; ... fp := @CompatibleFunc; ... The double dereference the poster uses above is not necessary. If anything, the fact it works in Delphi is questionable.
