I'll chime in. None of boost::{shared,scoped}_{ptr,array}<T> allocate
T instances within their constructors. That's (part of) what
make_shared is intended to do. Avoiding redundant type specifications
is auto/BOOST_AUTO's job. Rather than adding potentially ambiguous
constructor overloads to well-defined, heavily-used classes, spend the
time implementing boost::make_{shared,scoped}_array instead. auto +
make_{shared,scoped}_array will accomplish what you want (avoiding
specifying the type twice) and the functionality will benefit a much
broader audience.
