I wish for a better BOOLEAN operation within the IF statement.

[PascalDragon]

operator implicit is not available for stand-alone operators as in mode objfpc, afaik. Just := and that one is here also a compiler intrinsic. I haven't tested yet if maybe longbool is available.
[edit] nope..

The implicit operator is declared by the := operator overload. The explicit one uses Explicit like in Delphi.

Yes, but that is also taken by the compiler, hence the hardcast already works.
And as such these four all fail with impossible operator overload:

Code: Pascal  [Select][+][-]

1. {$mode objfpc}
2. operator explicit(const value:integer):Boolean;
3. begin
4.   Result := value <> 0;
5. end;
6. operator :=(const value:integer):Boolean;
7. begin
8.   Result := value <> 0;
9. end;
10. operator explicit(const value:Longint):LongBool;
11. begin
12.   Result := value <> 0;
13. end;
14. operator :=(const value:longint):Longbool;
15. begin
16.   Result := value <> 0;
17. end;

Which is rather a pity, since assignment from integer to boolean doesn't work without a cast, so implicit seems not to work at all. Is this a bug, Sven?
Especially longbool implicit assignment from a longint has scenarios that are useful, like preventing execution of a division if a value evaluates to false.
