Is there any reason why constructors in object pascal can not be private?

Constructors aren't private in C++, either: `struct Foo { Foo() = default; };` – Kerrek SB Apr 10 '16 at 21:24

1you do not understand, @KerrekSB, have you tried to do a singleton in delphi/pascal? In c++ you can change constructor's visibility to private but in delphi that's not possible. – Wellington Silva Ribeiro Apr 10 '16 at 21:27

Ah OK Maybe [this is relevant](https://stackoverflow.com/questions/5392107/delphi-singleton-pattern)? – Kerrek SB Apr 10 '16 at 21:30

@KerrekSB, look a singleton pattern in this link you'll see the visibility of constructor as private: http://stackoverflow.com/questions/1008019/c-singleton-design-pattern – Wellington Silva Ribeiro Apr 10 '16 at 21:32

Why can't you declare your constructor private? – Sertac Akyuz Apr 10 '16 at 21:34

offcourse is relevant in delphi we should use tricks to have a singleton, because i can alwasys call the public constructor, thats goes against the standard used by many languages – Wellington Silva Ribeiro Apr 10 '16 at 21:37

To have a private constructor, you have to use a trick that declares a private constructor! ??? – Sertac Akyuz Apr 10 '16 at 22:28

@WellingtonSilvaRibeiro, not so, see the duplicate, more specifically Uwe's answer. – Johan Apr 11 '16 at 00:05

@SertacAkyuz, LOL missed that, thanks that's actually funny. :-) – Johan Apr 11 '16 at 00:38

1@KerrekSB: unlike C++, Delphi has a rooted class system, and constructors are inherited. So even hiding a constructor as private will still surface the root class's constructor, TObject.Create. That can not be properly hidden. – Rudy Velthuis Apr 11 '16 at 13:39
