4502	Comparison fails for enumerations wrapped in uniontypes	Per Östlund	Martin Sjölund	"See the attached script, which simply wraps an enumeration in a uniontype and then tries to compare it. The expected output is:
{{{
f: E.one
f: E.two
f: E.three
}}}
The actual output if no extra flags are given is:
{{{
f: f:
}}}
The bigger issue though is that when code generation is forced on with '-d=noevalfunc,gen', representing what happens if you try to do something like this in the compiler, the output becomes:
{{{
f: E.two
f:
f:
}}}
If the function is rewritten to use a match instead:
{{{#!mo
function f
  input UT ut;
protected
  String s;
algorithm
  print(""f: "");
  s := match ut.e
    case E.one then ""E.one"";
    case E.two then ""E.two"";
    case E.three then ""E.three"";
  end match;
  print(s + ""\n"");
end f;
}}}
then it behaves correctly when code generation is forced on but still gives the same output when using interpretation."	defect	new	critical	Future	MetaModelica
