I mean that nested struct Point2D has additional pointer to frame and 
when compiler tries to instantiate template function 'tweet' it can't do 
it because in general it doesn't know about this additinal pointer to 
frame? And making it static I make it a general structure without 
additions and in this case compiler manages to instantiate 'tweet'?
