Description Iain Buclaw 2016-01-31 15:11:36 UTC 
Example:
---
void f()
{
    scope A a = new A();
    delete a;
}
---

Produces the following codegen, which is not entirely desirable.
---
void f()
{
  A a = A.init;
  __ctor (&a);

  _d_callfinalizer (a);
  _d_callfinalizer (a);  // Call always inserted by the compiler.
}
---

See here for when it came up.

Comment 1 Nick Treleaven 2022-05-30 13:36:32 UTC 
Presumably this can be closed now `delete` is gone:

Error: the `delete` keyword is obsolete
Comment 2 Iain Buclaw 2022-05-30 16:58:02 UTC 
Yes.
