First I'd like to thank you and all the contributors of the library for all your work done so far.

Going further, I'd like to propose making the library available through vcpkg (and other package managers) to ease up the process of integrating it on different projects, let them be existing or new ones. The library is header-only so should be (relatively) easy to integrate and sol2's "model" cou

template<typename T>
constexpr auto operator()(T&& t) const
CJDB_DEDUCE_NOEXCEPT({
   return process(t);
})

is much easier to grok and makes the function feel more natural than what is currently in place.

Proposed resolution

1. Replace definition of CJDB_NOEXCEPT_RETURN with

#define CJDB_INJECT_LAMBDA(...) [&] __VA_ARGS__ ()

#define CJDB_DEDUCE_NOEXCEPT(...)
