The constant Tips\Moduler\TT::TT_MATCHANTAL was not found. Maybe you did not declare it correctly or list all dependencies?

It seems like str_split($kodord) can also be of type true; however, parameter $array of array_map() does only seem to accept array, maybe add an additional type check?

				$temp = $nollrad;

				match ($index) {

Are you sure the usage of $this->helgarderingar($kod, $temp, $kod_helgarderingar) targeting Tips\Moduler\TT\TTReduceradKod::helgarderingar() seems to always return null.
