Hi,

The next step: meta level support.

Imagine you put a link in a method like OrderedCollection>>#add:, and then the meta level itself class that method again… endless loop. This e.g would happen easily if you would use a link to put a watch-point somewhere...

With this Slice:

https://pharo.fogbugz.com/f/cases/15447/Links-with-MetaContext

MetaLinks now can optionally model the meta-level: when calling a link, it is increased. This happens only when setting a level explicitly with #level: like here:

link := MetaLink new metaObject: <something>; selector: #someSelector level: 0.

Keep in mind that it is fairly heavy, using a Process-Local variable.

On the TODO:

-> support for links on primitive methods (by wrapping them) -> parameters for conditions -> parameters for the method called on the meta object -> “symbolic” meta objects #object, #node and #class -> links on Slots -> links on Globals

and of course breakpoints, we have now everything already that we need.
