@RobertHarvey serious actually. I've seen it so much times "moderators" closed this that whatever question, and I can't recall even single case when I saw a not-too-experienced reader would say "5 high-rep suckers closed it". To them, closures are all about "mods"
@RobertHarvey No, it has no purpose, it's purpose is "Because my interface made me, even though I can't", I'll comment it but it's still dirty because a consumer won't know whether they'll get an implementation that does support Count or one that doesn't now that there is one that doesn't
@RobertHarvey ...actually, recalling my first year or something at SO / Programmers, I can tell to me it was definitely so. Closures were "magic done by them mods". As opposed to this, comments never felt that way. Comments were all familiar stuff, I knew what it's about from other "forums" experience. Comments never were magic
One shaft of light that shows the way No mortal man can win this day It's a kind of magic The bell that rings inside your mind Is challenging the doors of time It's a kind of magic
This flame that burns inside of me I'm hearing secret harmonies
