Hi everyone,

I believe you should be able to do this transformation with Rewrite Tool.
The only problem I see is that you want to do this only with single symbol.��
Because, in my tool you can do:��

transform: `#literal into: `#literal aMessage.
In this case��`#literal means any literal, not only symbols.
In other words it will transform��

$a into����$a aMessage

Also, this rule will transform, for instance��
123 into 123 aMessage

If I understand right, you would like to do this programatically, so you don't need RewriteTool in that case.

If you don't want to manually operate on AST, you can use Mark's Rewrite Tool (��http://screencast.com/t/LCEl0hFl ,��https://medium.com/@peteruhnak/using-rewrite-tool-for-fixing-deprecated-code-12a595b291d8 )

As for ASTs I would be also curious about the answer, as this seems like it should be a simple task.

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? :)
