I am curious about what is the rationale for this. I have made it a pride 
that GridFlow produces combined values whenever possible, keeping in mind 
that as GridFlow evolves, it becomes easier and easier to use those 
grouped values instead of separate ones.

It used to be that [#export_list] -> [unpack 0 0] was necessary to pick up 
those values as floats, or [#export_list] -> [$1( and such, but on 
Michal's request I added an [#unpack 2] which makes this shorter, and I 
very much agree with him.

Part of the idea behind using values combined into a grid coming from only 
one outlet, is that #centroid could also work with differently-sized 
arrays without having to be explicit about it. (variable number of outlets 
currently require that the number of outlets can be guessed from the 
contents of the objectbox)

What do you think?

And if you think your idea is still good, which other objects should also 
have those extra outlets? (i'm thinking about consistency, which improves 
guessability, which improves acquired-intuitiveness)
