lgtm! is there some documentation that needs to be updated for this? Maybe a tutorial? We can update here, or merge after opening a new docs issue (only if necessary).

@fadeev do you know if the colon syntax is documented somewhere? I can't find any reference, usage or example, so it seems that the colon syntax was a hidden feature :)

@jeronimoalbi no, I submitted a pr to add docs, but then proposed to actually change the behavior instead.

@aljo242 I we don't really need to update the documentation because the colon syntax was not documented. We could improve the current one, I guess, but right now I'm not entirely sure how.
