return vs return nothing

[simeonschaub]

I don't have a strong preference either way, but I think it would be nice if Runic normalized to one or the other. The only potential issue is that it's technically possible to redefine nothing inside a module or function, but I have yet to see any code in the wild which does this.

Re #48 (comment):

I would argue that even in the case of 2., the function still returns a value of nothing, irregardless whether it's used or not, so I would say making that explicit via return nothing is not necessarily bad

FWIW, I'd also vote for normalising to return nothing. In addition to @simeonschaub's point above, to me, the (subtle) communicative aspect of distinguishing between return and return nothing is outweighed by the advantage of clarity and consistency.
