repr(VARIANT.missing) raises NotImplementedError

[junkmd]

It is very inconvenient when debugging, so let's add elif self is type(self).missing to __repr__.

comtypes/comtypes/automation.py

Lines 205 to 208 in dbe4fa1

	def __repr__(self):
	if self.vt & VT_BYREF:
	return "VARIANT(vt=0x%x, byref(%r))" % (self.vt, self[0])
	return "VARIANT(vt=0x%x, %r)" % (self.vt, self.value)

    def __repr__(self):
        if self.vt & VT_BYREF:
            return "VARIANT(vt=0x%x, byref(%r))" % (self.vt, self[0])
        elif self is type(self).missing:
            return "VARIANT.missing"
        return "VARIANT(vt=0x%x, %r)" % (self.vt, self.value)

I will work this while adding type hints to comtypes.automation.
