has the change.
invalidate
nodes do: [ :node | node invalidate ]
With this simple change, one can now use e.g. a boolean as a link condition:
haltLink := MetaLink new
condition: false;
metaObject: Halt;
selector: #now.
When installed, it does nothing. But we can afterwards change the condition:
haltLink condition: true.
and it will make sure to re-compile all affected code before the next execution and thus enable the
link. The same is true for #selector: and #metaObject:.
