In Visual Studio 2012 and the .NET Framework 4.5, any method that is
attributed with the async keyword (Async in Visual Basic) is

Case objects vs Enumerations in Scala
...es. However, I find in general that enumerations are a bit clumsy in Scala and have the feel of an awkward add-on, so I now tend to use case objects. A case object is more flexible than an enum:
sealed trait Currency { def name: String }

Personally, I like to think about what FRP means before addressing how it might be implemented.

PHP function overloading
... overload PHP functions. Function signatures are based only on their names and do not include argument lists, so you cannot have two functions with the same name. Class method overloading is different in PHP than in many other languages. PHP uses the same word but it describes a different pattern.

Is the Scala 2.8 collections library a case of “the longest suicide note in history”? [closed]
