Whilst we are on the subject: Why is the constructor
that accepts an std::auto_ptr not explicit ?

Subject: [boost] Always explicit , why?

I've been using a reference-counted pointer class extensively in my
c++ programs, and I'd like to switch completely to boost::shared_ptr.
But there's one thing that puts me off: The constructor that accepts
a raw pointer is declared "explicit".
When you're passing around pointers as shared_ptr parameters, it's
just unnerving always having to provide the explicit ctor-call.
I couldn't come up with a compelling reason why this should be
necessary. When there's a function that expects a shared_ptr<Type>,
why not provide it simply a "new Type()"?
Am I overlooking any ambiguities or unexpected behavour that could
result from removing the "explicit" from shared_ptr's ctor?
Or is it plainly considered heresy to deviate from Standard
Library's "auto_ptr" pattern ;-)
