This is worth knowing...

OK I just tried added a nested method that destroys the instance and it shows that the type isn't killed until the original method is exited, not just the nested one, which is to be expected:

Strict
Type TTest
	Method Bang()
		Nested()
		Print "nested"
	End Method

	Method Nested()
		KillTest()
		Print "hello"
	End Method
		
	Method More()
		Print "more"
	End Method
End Type

Global t:TTest = New TTest

t.Bang()
't.more() 'uncomment this line

Function KillTest()
	t = Null
End Function
