Call expressions whose this changes are not updated

[justinbmeyer]

Something like: {{ this.todo.isSaving() }}

Doesn't work if this.todo is updated but the same .isSaving method exists on both.

Shouldn't the whole expression re-evaluate in this case?

[justinbmeyer]

@matthewp well, it depends on what "whole expression" means ...

a.outerCall( b.innerCall( c.superInner( arg1) ) ) 

If a changed in a.outerCall, we should not re-evaluate any of b.innerCall( c.superInner( arg1) ).
