boost::hof::construct to support aggregates

[Aster89]

I've discovered BOOST_HOF_LIFT/BOOST_HOF_LIFT_CLASS some time ago, and it's very useful when I want to make an object out of the name of a templated and/or overloaded function.

Then I've discovered boost::hof::construct, which helps me avoid writing [](auto x){ return Ctor{x}; } all over the place.

But almost immediately I run into the issue that boost::hof::construct can't be used with aggregate types (sorry if I'm misusing the term, I mean those that don't have a user defined constructor; if I understand this, that's what an aggregate is, but correct me if I'm wrong).

I know that HigherOrderFunctions is a header-only C++11/C++14 library, but the point is that using class names as object is not possible in those standards, but not even in C++17, or C++20, for what is worth, so BOOST_HOF_LIFT/BOOST_HOF_LIFT_CLASS/boost::hof::construct are still all useful in those newer standards.

So my bottom line is, why not upgrading boost::hof::construct so that it can work with aggregate types too (in C++17, where std::is_aggregate) is available?
