Having the opening and closing braces {{{ ... }}} can actually be pretty useful, if you're a vim/gvim user.

It implements a mechanism called "folding", whereby one can "fold" multiple lines of text into a single physical line on the screen, making it easier to read the program as a whole.

I can see why it might be distracting if you weren't a vim/gvim user, but its advantages, IMO, far outweigh its disadvantages for those who use this mechanism.
