What does this implement/fix? Explain your changes.
Was:
tp_newimplementation would call .NET constructor and return a fully constructed objectNow:
Except for some special .NET types
tp_newcreates uninitialized .NET object, which is later initialized by callinguninitialized_inst.__init__(...).__init__is set in type dictionary to aMethodObject, that containsConstructorInfo[]instead ofMethodInfo[]This allows Python to:
__init__when deriving from .NET types__init__(e.g. .NET constructor), and choose the overload as neededFailing to call base
__init__in this scenario will lead to an undefined behavior.Does this close any currently open issues?
fixes#238
