Thank you for your reply.
If this characteristic is a design of DMD, I will close this bug report.
What do you think that both look like asymmetry?
import std.stdio;
class Base
{
int f() {return 0;}
int g() {return 0;}
}
class Derived : Base
{
private override /+int+/ f() {return 1;} // accepts
public override /+int+/ g() {return 1;} // rejects
}
void main() {}
main.d(10): Error: function main.Derived.g of type () overrides but is not
covariant with main.Base.g of type int()
main.d(10): Error: function main.Derived.g does not override any function

When you use enum, override and few other things, DMD performs type inference, so the explicit return type is not necessary. So I presume this bug may be closed. (If you think this D characteristic is leads to many bugs then this bug report may be kept open, despite the probability of seeing it fixed is low.) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
