Re: 3.0.1a3: global classes

Classes in "common" bundles are global, yes. Consider the following
example:

body common control
{
bundlesequence => { "g","tryclasses_1", "tryclasses_2" };
}

#################################

bundle common g
{
classes:

  "one" expression => "any";

}

#################################

bundle agent tryclasses_1
{
classes:

  "two" expression => "any";
}

#################################

bundle agent tryclasses_2
{
classes:

  "three" expression => "any";

reports:

  one.three.!two::

    "Success";
}


What is arguably misleading at the moment is that the common
bundle also must be in the bundlesequence in order to be evaluated.
This is not true for variables, which get evaluated anyway. I am in
two minds as to what the behaviour should be. The evaluated is fraught
with potential paradoxes unless this is explicit. There is a
chicken-egg issue in what should be evaluated first - vars or
classes.. I'll think about this.
