          Issue ID: 14113
           Summary: Lexically first function is picked as overriding one
                    even if it's `const` and base one isn't
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal

         Component: DMD

This code should compile:
---
class A
{
    abstract void f();
}

class B: A
{
    override void f() { }  // no errors here
    void f() const { }
}

class C: A
{
    void f() const { }     // line 14
    override void f() { }  // line 15
}
---
main.d(14): Deprecation: implicitly overriding base class method main.A.f with
main.C.f deprecated; add 'override' attribute
main.d(15): Error: function main.C.f multiple overrides of same function
