Let's say I have the following:


const boost::shared_ptr<int> x;

What's const? The smart pointer itself, or the data it's pointing to? And what about this:


boost::shared_ptr<const int> x;

1: The smart pointer itself. 2: The data it's pointing to.

It's exactly what it looks like, if you read < as "to" and > as "".

a const smart pointer to an int; a smart pointer to a const int.

Well, the confusion came from regular pointer syntax:

const int* x

Means that the the data pointed to by x is const, not x itself.
