4 in order to keep these ref's during re-evaluation of code,

682 # How to manage theorys in subproblems wrt. the requirement, #
683 # that scripts should be re-usable ? #
684 #############################################################################
686 eg. 'Script Solve_rat_equation' calls 'SubProblem (RatEq',..'
687 which would not allow to 'solve (y'' = -M_b / EI, M_b)' by this script
688 because Biegelinie.thy is subthy of RatEq.thy and thus Biegelinie.M_b
689 is unknown in RatEq.thy and M_b cannot be parsed into the scripts guard
692 Preliminary solution:
693 # the thy in 'SubProblem (thy', pbl, arglist)' is not taken automatically,
694 # instead the 'maxthy (rootthy pt) thy' is taken for each subpbl
695 # however, a thy specified by the user in the rootpbl may lead to
696 errors in far-off subpbls (which are not yet reported properly !!!)
697 and interactively specifiying thys in subpbl is not very relevant.
699 Other solutions possible:
700 # always parse and type-check with Thy_Info_get_theory "Isac"
701 (rejected tue to the vague idea eg. to re-use equations for R in C etc.)
702 # regard the subthy-relation in specifying thys of subpbls
703 # specifically handle 'SubProblem (undefined, pbl, arglist)'
