Hi everyone,

I would like to modify the AST of a smalltalk expression compiled to automatically send a certain message
when a node represents a Character (so the user does not have to write the message sending explicitly).
I would of course add a special button in the menu you get when right clicking in a playground so the user
knows it is a "special" do-it...

For example:
�� �� $a.
would transform into an ast that the source code looks like
�� �� $a aMessage

How can I do this? :)
