`make` overloads

== Synopses

Declared in `<bslma_constructionutil.h>`

Return, by value, an object of the specified (template parameter) `TARGET_TYPE`, having default value. If `allocator` is a `bslma`‐compatible allocator and `TARGET_TYPE` supports `bslma`‐style allocation, `allocator` is passed to the extended default constructor; otherwise, `allocator` is ignored. Note that this method is available only for compilers that reliably implement copy/move elision (i.e., RVO) on the returned object. This copy/move elision is required starting with C++17 and is widely implemented, though optional, prior to C++17.

Return, by value, an object of the specified (template parameter) `TARGET_TYPE`, constructed by forwarding the specified `argument1` and the (variable number of) additional specified `arguments` to the corresponding constructor of `TARGET_TYPE`. If the specified `allocator` is a bslma‐compatible allocator and `TARGET_TYPE` supports `bslma`‐style allocation, the allocator is passed to the constructor; otherwise, `allocator` is ignored. Note that this method is available only for compilers that reliably implement copy/move elision (i.e., RVO) on the returned object. This copy/move elision is required starting with C++17 and is widely implemented, though optional, prior to C++17. Note that, in C++03, perfect forwarding is limited such that any lvalue reference in the `arguments` parameter pack is const‐qualified when forwarded to the `TARGET_TYPE` constructor; only `argument1` can be forwarded as an unqualified lvalue.
