How to get CLR type of Python class?

Prerequisites

• Are you running the latest version?
• Are you reporting to the correct repository?
• Did you perform a cursory search?

Description

So, we have as task getting CLR type of strongly typed class in IronPython, if possible, without invoking constructor. Example:

class Vehicle(Component):
    __metaclass__ = clrtype.ClrClass

    _Test = SpecialProperty[int]()

    @property
    @clrtype.accepts()
    @clrtype.returns(SpecialProperty[int])
    def Test(self):
        return self._Test

    def __init__(this, *args):
        return Component.__new__(type(this), *args)

Possible ways at now:

1. Create object of this type and invoke GetType() from it. Example:

CompiledCode compiled = source.Compile();
compiled.Execute();
var pythonType = compiled.DefaultScope.GetVariable("Vehicle");
var obj = ops.CreateInstance(type, new object[] { Guid.NewGuid() });
var clrType = obj.GetType();

1. Get base class type by accessing constructor. Example: var clrType = pythonType.__new__.Overloads.Targets[0].DeclaringType;
2. Playing with “internal” methods of IronPython, but it’s hard.

Affiliated problems and possible fixes

1. pythonType.GetType() throws System.MissingMemberException, but should return something like typeof(IronPython.NewTypes.IronPython.Runtime.Types.PythonType_2$2) or typeof(IronPython.Runtime.Types.PythonType).
2. pythonType.__new__.Overloads.Function.DeclaringType return System.Object, but by logic, should return proper containing type.
3. IronPython.Runtime.Types.PythonType should have reference to CLR type, if available.

I’m not sure I follow what the issue is. pythonType is a CLR type.

var scope = engine.CreateScope();
engine.Execute(script, scope);
var pythonType = scope.GetVariable("Vehicle");
var type = (Type)pythonType;
var obj = Activator.CreateInstance(type, new object[] { Guid.NewGuid() });
Debug.Assert(obj.GetType() == type);
Debug.Assert(obj is Component);
Debug.Assert(pythonType(Guid.NewGuid()) is Component);

@DjArt Looks like I was incorrect, pythonType is PythonType is correct. But the PythonType can be cast to Type.
