I realized that, as usual, I did not express myself properly. I should have
not split the two points in DEFSYSTEM and SHARED-INITIALIZE.

My actual complain was that there is no way to add options to a class and
let the class process the system definition based on them. Not really the
parsing: if DEFSYSTEM is implemented using SHARED-INITIALIZE and the class
gets the original form, then it could implement additional parsing steps,
such as ensuring that there is a configuration file for lift, or placing
some safety actions before and at the end of the test system.

I am not at all for classes changing the DEFSYSTEM grammar, or introducing
hidden dependencies themselves. That would go against any effort on turning
system definitions into descriptive files that can be processed
independently of any configuration one may have.

Thanks a lot for clarifying this point.
