Detailed Description

template<typename T>
class abg_compat::optional< T >

Simplified implementation of std::optional just enough to be used as a replacement for our purposes and when compiling with pre C++17.

The implementation intentionally does not support a whole lot of features to minimize the maintenance effort with this.
