Qualified tuple assignments in MetaModelica

[Karim Adbdelhak]

Following code inside an arbitrary match of an equation returning a qualified reference in a tuple does not work:

case eqn as BackendDAE.EQUATION() algorithm
  (eqn.exp,extArg) := SomeFunc(eqn.exp,extArg);
then eqn;

whereas replacing it by an artificial temporary and assigning it afterwards does.

case eqn as BackendDAE.EQUATION() algorithm
  (e,extArg) := SomeFunc(eqn.exp,extArg);
  eqn.exp := e;
then eqn;

It also works if the function only returns a single value.

This is the expected result. case eqn.exp as 3, etc will also not create such an object. (The assignment is an inline match)
