"Let's then remove _ as a digit separator because of grep." \- It's not as common to grep for numerical values as for names.
I don't care much if there's a vote or not, but I really don't think it should be changed. But I do think Nim should issue warnings about difference in style though. I think it should mainly be used as a way to allow people to have less of a mental overhead when programming and debugging. But it would be nice to encourage people to take a pass over the code later, so it's more pleasant to read and easier to debug. Maybe a gofmt-like tool could help people align this
