--- Comment #1 from moonlightsentinel at disroot.org ---
This seems to be a regression that was fixed for some time:

Up to      2.064  : Success and no output
           2.065.0: Failure with output: onlineapp.d(3): Error: associative
array key type const(Key) does not have 'const int opCmp(ref const Key)' member
function
2.066.0 to 2.079.1: Success and no output
Since      2.080.1: Failure with output: onlineapp.d(3): Error: AA key type
`Key` does not have `bool opEquals(ref const Key) const`

The second regression was caused by https://github.com/dlang/dmd/pull/7982
