That is a facet of programming culture. So many programmers in so many languages have their silly myths. A few years some Ruby dev said that declaring methods without parenthesis would let the Ruby parser parse method declarations faster. The dev never even measured, he just thought the parens were ugly and a ton of gem devs removed parens claiming a speed up. It wasn't until a few years later that someone benchmarked it and determined that there either was no difference or that it cost just the tiniest amount to remove them.
