Smaller changes are easier to review, that is obvious and I support it.
For what do we have the `ShortBlocks` anyway? If `If` and `Loops`, enums, cases, etc. are handled separately, what is left?

@rudolflovrencic I have no problem with adding the options. But when you want to invest some time in the area can I make a small request? I have always had a problem with the name `Allow...` because it doesn't allow, it forces either way. Allow would in my eyes be `Leave` like we have in other options. There would be 2 ways to handle it, either keep the name and add a `Leave` option, or change the name (and then it's still open to add `Leave`).
