In this case, the pattern is simple is there a trailing return type and does it
use decltype with a template function and is that template function defined
(and in that scope or outer scope) then this will be a dup of that issue. (it
is only valid C++20 rather than being valid C++17 too).

Hope that helps. 

Also note C++20 support in GCC is still being fixed in many areas too so using
GCC 11 which came out less than 4 months after C++20 was ratification and
published is definitely going to be an issue.
