And now I feel very dumb.

You were right :/ It's all fixed now, thanks a lot for reporting.

(At first I thought that you thought that return type specification was non-optional, e.g. that it lacked "-> Void")

About the other issues: are you really bothered by them? (e.g. the familiarity of the writing, etc.) I thought it'd be less boring, but I didn't mean it to annoying.

EDIT: fixed the "strange little dots" and "compiler is your friend" parts.
