You find C# harder than this? trait SeqLike[+A, +Repr] extends Any with IterableLike[A, Repr] with GenSeqLike[A, Repr] with Parallelizable[A, ParSeq[A]] { self => or def :+[B >: A, That](elem: B)(implicit bf: CanBuildFrom[Repr, B, That]): That

Thank you! I'm working on a team that inherited some Scala code from contractors that no longer work for us and we've found that (at least their) Scala is almost as hard to read as bad Perl. Compounding this is a severe lack of good online documentation outside of the standard library reference and simple tutorials which don't go into the depths we need to know (like how do you create a Manifest from Java to call int…

It's funny how Nadella has moved the needle more for developers in 9 months than Ballmer did in the last decade or so, and all that without running around like a madman too. Pretty good. I'll never switch back to MS for what they've done in the past but it is nice to see them try hard to become a nicer player in the software eco-system. Google and Apple need some other party to keep them sharp, it might as well be MS…

Seeing comments like this “I'll never switch back to MS for what they've done in the past” always reminds me of this post from Hanselman http://www.hanselman.com/blog/MicrosoftKilledMyPappy.aspx

That's true. A talented C# dev will need to know co/contravariance as well as implicits considering they also exist in C#. In Scala, being familiar with these concepts is practically a necessity, though.

Can you give me examples of implicits in C# ? I am unable to see a parallel.

  using System;
  
  public class Program
  {
  
  public class Person
  {
    private string _name;
    private int _age;
    
    public Person(string name, int age)
    {
      _name = name;
      _age = age;
    }
		
    public static implicit operator int(Person p)
    {
      return 42;
    }
  }
	
  public static void Main()
  {
    var person = new Person("Jim", 51);
    var number = 100;
    AdditionPrinter(person, number); // Prints 142
  }
	
  public static void AdditionPrinter(int a, int b)
  {
    Console.WriteLine(a + b);
  }
  
  }

It is easier, there is only one concept to understand : generics, with scala you must understand generics, co and contra-variance, implicits.
