Hi,

Following Pharo Days, I brainstormed about some possible class definition syntaxes.
What I have in mind:

"basic mechanics, only THIS one in the image!"
ClassDefinition new
superclass: Object; "optional. If not specified, Object by default ;-)"
name: #A; "optional and create an anonymous class if not specified"
instVars: 'a b c';��
traits: {TEquality};
package: 'Plop';
createClass. " this message sent might be hidden by the browser when accepting"

"---------------"
"Some IDEAS (but I did not find one that I really like) of scripting/shorter syntaxes that must ALWAYS end up calling the above basic mechanics at the end:"

Class fromDefinition: [ :def |
def name: #sub;
instVars: 'w r g';
superclass: Object ].

Object subclass ��"<-- returns a subclass of Object but the problem is that the new class is muted

(btw, I assume you mean mutated.) ��
��
each time and the class definition is not explicit"
name: #A;
ivs: 'a b c';
traits: { TEquality }.

What about...

�� ��Object subclass: [ :def | def
name: 'MyClass' ; �� �� ��"optional and create an anonymous class if not specified"
instanceVariables: 'a b c' ;
�� �� �� �� classVariables: 'M N O';��
�� �� �� �� classInstanceVariables: 'x y z' ;
traits: {TEquality} ;
package: 'Plop'].

�� ��Object>>subclass: builderBlock
�� �� �� ��^ (builderBlock value:��ClassDefinition new)��createClass
�� �� ��
or similar to Guille's declarative proposal...

�� ��Object subclass: {
�� �� �� ��name: 'Myclass',
�� a: InstVar,
�� b: InstVar,
�� �� �� c: InstVar
�� ��}
