Hi,

With Miguel Campusano we build a small demo.

There is a "Execution Metalink Demo” Plugin for Nautilus. 

        "A demo of Metalink usage: when it is installed, it glows red when the 
selected method is executed somewhere in the system”

If you install it and open a new browser, there is a strange morph in the 
middle position. every time you select a method, it installs
a meta-link there that calls a method on the morph to make it red. Then the 
morph has a #step method to get darker step by step.

-> activate the plugin
-> open new browser
-> go to Array>>#asArray and see how it glows e.g. when moving the window

Note: 
        -> if you select the “right” methods, the image will freeze 
(meta-recursion, we do not use meta-level aware links yet)
        -> somehow the metalinks do not get GCed (but it seems the actual 
de-installing works).

The idea is that it is for now just a demo… but when the framework gets stable, 
it is an example of what we can do with it.

        Marcus
