Closures is a language that allows people to write in different ways. Aps flier's main development language is a closure, and it was three years ago when i just joined. It wasn't love, love at first sight but i learned to love closer. And now i have a big, big place in my heart for closure. So they saw parenthesis for the first time. And i hope that is going to change them forever. After thatof course, sure it will.
