> @HighCommander4 could you explain what exactly this fixes? The change seems simple, but from the tests I cannot tell that any behaviour actually changed and moreso the internal representation of a struct tempalte. Also the link to the "issue" seems unrelated to me? At least I am very confused what in that discussion is the issue.

@timon-ul Oops, I linked to a totally unrelated issue :/ Fixed now.

Hopefully my comments in the issue make it clear what's going on... let me know if you still have questions!
