Not sure if C++20 is officially supported right now.

When compiling through clang-1300.0.29.30 with C++20, the following error occurs:

.../etl/include/etl/memory.h:979:30: error: use of undeclared identifier 'o'
    return std::construct_at(o, etl::forward<TArgs>(args)...);

Looking at the code, there seems to be a missing definition for o?

For now, I worked around by using #define ETL_CPP20_SUPPORTED 0.

There's a typo. the o should be p. This will be fixed in the next release.
