+! Fluid Class Defintions In Pharo 12
+
+Marcus Denker (marcus.denker@inria.fr)
+
+""Abstract:""
+
+With Pharo12, the Fluid Class Definition format is now the default. 
+
+We will first look back at the traditional Smalltalk-80 class defintion format and show the problems that it has. 
+
+Then we present the Pharo Fluid Class Defintiona and show how it solves these problems. We discuss how the Fluid format works hand in hand with First Class Variables. 
+After some examples of Fluid in Pharo12, we discuss what Fluid could enable in the future.
