Re: std.container and classes

[Froglegs]

  I don't really think ref counted struct vs class is fair, 
because in reality most containers don't need ref counting.  I 
can't think of one instance in C++ where I stuck a container 
directly in a shared_ptr or anything similar.

Also as far I as I can tell making it a class would bloat it with 
unnecessary data(vtable), and being it is common to have many 
many instances of these containers, that doesn't sound like such 
a great thing.
