You use parenthesis to group mathematical expressions in Julia. I thought had made that clear. If not maybe you could quote something giving a different impression, so I can fix it.

The point I was making in the article was that you should reserve symbols such as { and ( for expessions you need on one line.

My point was that you can use keywords to denote scope, because you don't need write lots of scopes on one line.

I'll add multiple conditionals to the article if that helps.
