Congrats on the release. I've been following your progress, and saw
good stuff in your commits.

Could you please more clearly state in the project's README.md the
minimal version
of C++ required, and whether the interface or impl changes with higher
versions of std?

Your hello-world example (extracted below), uses lambda-auto (C++14),
probably variadic templates (C++11 and up, C++17 for
fold-expressions), etc... So if you require C++20,
that's important to know (since out of bounds to me, for example).

In the same vein, what platforms / compilers / versions it's built and
tested on is also useful to know upfront.
(again, as an example, I need to be cross-platform and cross-compiler,
including Windows and MS VS).

My $0.02. And thanks for sharing your work. --DD
