2072	intialization of output formal parameters in modelica functions	Willi Braun	Martin Sjölund	"I guess we should set an implicit default value for formal output parameters, even if I haven't found that sentence in the spec. Of course, that's bad modelica code and we should try at least to warn the user, but I think the MSL is full of such stuff. 
What do you think?

Example:
{{{
function f
  input Real x;
  output Real a;
  output Real b;
algorithm
  if x > 0.5 then
    a := sin(x);
  else
    b := cos(x);
  end if;
end f;

model A
 Real x,y,z;
equation
 der(x) = x+y+z;
 (y,z) = f(time);
end A;
}}}


BTW.: This is also the reason for our mysterious failing of simulation_libraries_msl32.Modelica.Electrical.Spice3.Examples.Nor.mos 
with the clang compiler.
