I personally find that I end up reading more lines of code than I need to.

When scanning and I see

    If (condition) { perform_some_action(foo, bar, baz); }

And I know condition is false I can ignore what follows but

    perform_some_action foo, bar, baz if condition

I now have to stop and parse the entire line. But not only that, because it can appear at the end I need to parse every line to make sure I don't get caught by some if or unless. Short lines are easy sure but it's still annoying to me.
