hi, what about xkcd4:ⅽⅿⅹⅹⅶⅹ or xkcd5:٩٢٧ (note: may not appear in correct reading order due to technical limitations)

I propose a browser powered by deep machine learning that lets you just write 927 and automatically figures out that it refers to an XKCD by inferring the context from looking at the content on the rest of the page.
