[Boost-users] shared_ptr<> null deleter

I have just discovered to my delight that you can use shared_ptr with  
a null deleter to pass around stack based objects. This is great  
because a function shouldn't care whether a parameter passed to it is  
on the heap or stack. So I can write general functions to accept a  
shared_ptr and if I have to pass a stack based object I can just pass  
a null deleter.

My question is whether the boost library has anywhere in it a null  
deleter object, or whether it is possible to define one in place with  
boost::lambda or similar? It seems silly that something that I imagine  
would be needed quite commonly is not included in the library.

Thanks,
Kevin Martin
