Many, many thanks to Daniel Murphy for slaving away for 2.5 years to make this happen. More thanks to Martin Nowak for helping shepherd it through the final stages, and to several others who have pitched in on this. This is a HUGE milestone for us. Much work remains to be done, such as rebasing existing dmd pull requests. Thanks in advance for the submitters who'll be doing that. I hope you aren't too unhappy about the extra work - it's in a good cause! Should we be looking to put out a DMD 2.069 beta to get more hands on testing it early?

On the other hand, I'm curious to know why you chose D to make this announcement?

For example: abstract class BaseA { abstract void foo(); } class A : BaseA { override void foo() { } virtual void foobar() { } } All is well. But then BaseA (which may be in a different library), suddenly becomes: abstract class BaseA { abstract void foo(); virtual void foobar() { dostuff(); } } Now you have A, which has foobar, but isn't actually related to BaseA.foobar. You probably didn't mean to override foobar, but it's still confusing for anything expecting BaseA.foobar to be related to A.foobar. You might not even know BaseA.foobar was added if it was part of a different library. Or, even worse: class B : A { override void foobar() { dootherstuff(); } } It definitely gets a bit odd, and new is there just to prevent confusion / clarify intentions, as well as let you know when a new method is added with the same name. The whole situation is messy, like what happens when A.foobar is removed and you suddenly start overriding BaseA.foobar instead. Or what if you were intending to override BaseA.foobar, but now you're suddenly overriding A.foobar once A adds the method? I'd actually prefer to specifically have to write 'override void A.foobar()' if A.foobar is marked as 'new' for this reason and make it an error to not include new or override when dealing with the same name. D could probably benefit from this approach as well, for the same reasons.

I wasn't aware of this restriction. https://github.com/D-Programming-Language/phobos/pull/3572 OK, I dug into it further. It seems that under some level of detection of whether a function that could be called on the base is really called on the derived, then the derived function is not allowed to mask the base function. HOWEVER, if the call would result in an error instead, then the override is totally fine, and calling the function on a base reference actually calls the masked function. This seems incorrect, when you mask a function, I would consider that to be hidden also. So technically, the error is that the toString masking could be called in the same way the base could be called (given the default parameter). This sure seems arbitrary to me. I remember the whole thing about function hijacking, but this hidden function "feature" doesn't make a lot of sense. In one case, you can hide it, but still access it from the base, in another, the compiler was rewriting the vtable to not allow you to access it from the base, on what seems to be an arbitrary concern. And that now is a compiler error. I wonder how this will affect multiple alias this, since you could potentially have a type that converts to two disjoint types, but wouldn't be known to the compiler if a base and derived class accepted the disjoint types. -Steve

It's not that phobos is bad, it's that we're following the same development pattern we had with C++. We're using a conservative subset of D features and libraries, and slowly expanding what's acceptable. For example, DMD now uses foreach and delegates in a few places, and I expect we'll see a lot of use of D strings in the near future.
