Smalltalk inspired extensions for c#

Having developed in Smalltalk for about 3 years in the early '90's, I still regard the language fondly and am always slightly saddened that it never achieved mainstream adoption.Without Smalltalk, I don't believe I would have so 'easily' became moderately proficient in object oriented thought - note, not analysis or design, but literally thinking 'as an object'. Anthropomorphising is still something I engage in.

Philosophy aside, I amused myself by considering the behaviour of the Smalltalk boolean object a few weeks ago after a brief period of development in Squeak (see also below). You 'talk' to the boolean, and can effectively ask it to do something if it is true or false.

A simple example below, that writes a message to the Transcript window depending on the outcome of the test (which returns a boolean):

 a > b  
 ifTrue:[ Transcript show: 'greater' ]  
 ifFalse:[ Transcript show: 'less or equal' ]  

So, being perverse, what could I do to mimic this behaviour in c#, so I might be able to say:

 (a > b)  
   .IfTrue(() => Console.Write("greater"))  
   .IfFalse(() => Console.Write("less or equal"));  

It's obvious really - use an extension method on the System.Boolean type. This is shown below:

 public static class BoolExtension {  
          public static bool IfTrue(this bool val, Action action) {  
              if (val) action();  
              return val;  
          }  
          public static bool IfFalse(this bool val, Action action) {  
              if (!val) action();  
              return val;  
          }  
      }  

Please don't misinterpret - I'm not espousing this as a necessarily good idea, more demonstrating that extension methods allow one to 'fake' the presence of interesting constructs present in other languages.

From the squeak website:
Welcome to the World of Squeak!Squeak is a modern, open source, full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change. Squeak is the vehicle for a wide range of projects from multimedia applications, educational platforms to commercial web application development.
