Is there in scala the equivalent of the c# nameof?

Question

In c# I can write code such as this (I ran it Linqpad 5):

void Main()
{
    new Test { Property1 = 100 }.Dump();
    Console.WriteLine(nameof(Test.Property1));
}

class Test
{
    public int Property1 { get; set; }
    override public String ToString()
    {
        return $"{nameof(Property1)}={Property1}";
    }
}

Is there a scala equivalent of nameof?

Thanks

@pedrofurla The benefit of `nameof` is that it is turned into a string at compile time but it otherwise still a symbol reference so can be reliably refactored with the source property. — Richard Szalay, Jun 30 '17 at 02:01

@Frank: My goal is to avoid using magic strings. nameof in C# probably has support from the compiler. — boggy, Jun 30 '17 at 02:13

In Scala it can be done by a (macro) library instead of needing special language-level support. There is one at https://github.com/dwickern/scala-nameof.

There is no any similar methods in scala as of C#, If you really want the function than you can use scala-reflection.
