Hi folks,

I've this:

/Users/frak/dlang/ldc-1.23.0/bin/../import/std/traits.d(3711): Deprecation: function `std.typecons.Nullable!long.Nullable.get_` is deprecated - Implicit conversion with `alias Nullable.get this` will be removed after 2.096. Please use `.get` explicitly.

I'm trying to find out WHERE this is generated to fix it, dependency included, without success.

Suggestions?

Because it's probably coming from a constraint, you probably can't figure out the exact usage. What's more annoying is that likely it is a spurious warning. A lot of traits "try something", and then alias to false or true depending on what works. But it's not going to make a difference in your code.

It's one of the most annoying things in the library. If you see this warning coming from *your* code, then you should fix it. But it will tell you the location if that was the case, not std.traits.

I've just ported my code to 2.094 and had to clean up that issue. Luckily, in my case they were all in user code. I had to access my Nullable objects with .get:

  if (n) {
    // n.foo();    <-- from
    n.get.foo();   <-- to
  }

So, look at all your Nullable objects maybe.

That's REALLY REALLY annoying! I'm spending LOT of time trying to figure out the exact point to fix in the code.

Any idea? dustmite?

You can give me access to the code and I can find it out for you.
That's the best I have.

Thank you, but unfortunately that's not possible

The problem has been observed already and it is an official enhancement request [1].
I think it is legit because deprecation are sometimes used to help into refactoring, so to have the use site is a essential.

Does compiling with -v help?  I think it might at least show you which module the issue is coming from?
