Funny fact is that I just discovered that we have
<https://nim-lang.org/docs/system.html#add%2Cseq%5BT%5D%2CopenArray%5BT%5D>
to add elements of an array to a seq. So I should be able to just write
lcuts = v.vertex.neighbors - (lcuts.add([u.vertex, w.vertex]))
Run
which is much better than adding the entities one by one for readability. And
as add() should not allocate performance should be not bad.
I had yesterday the feeling that we have only add() procs for single elements
but not for containers in the std lib. So maybe the initial post was indeed
silly. I will ask my Mom next time before posting :-)
