Cryptic error messages returned when checking a model

[Leonardo Laguna]

We have this very simple model (that is incorrect)

package Danne
  model M1
    parameter Real x=1;
    Danne.M2 m21(M31.m41.m51.x=2);
  end M1;
  model M2
    parameter Real x=1;
    Danne.M3 m31;
  end M2;
end Danne;

and when checking the model we obtain this error message that is very hard to understand:

Error: Variable m21: In modifier (M31 = (m41 = (m51 = (x = 2), class or component x), class or component m51), class or component m41), class or component M31 not found in <M2>

Is it possible to improve the printing of these type of errors?

I get: [a.mo:1:1-10:10:writable] Error: Class M3 not found in scope Danne., which seems reasonable.
