Once upon a time there was a heroic and brave mathematician than invented a whole new branch of mathemathics just to show how everyone around him were acting like wasteful idiots (sinónimo).
Since eveything was brand new, new words also needed to be invented; words that could describe to other smart people like him what they wanted to convey, in as few syllabes as possible.
Decades passed, and humanity sent all their brightest minds in a quest to give back potency to men way past their prime, instead of wasting their brilliance in dull endeavors, like finding methods to generate energy more easily.
Once such a noble goal was conquered, what other beasts were left to be slayed? Cancer, hunger...?
No. They knew there's no glory in slaying small beasts.
What humanity really needed were new methods to better satisfy the urges of the flesh.
And so, a new generation of heroes began to use the ideas of our legendary mathematicians of old.
Those old concepts were rebranded as the very best new thing that ever happened, and the excitement of people for these new weapons got so high, even old, brute warriors that knew more about bashing people's heads than the finesse of mind pursuits, began using those arcane words of power.
But the lowly peasants that could have surely benefited from these tools, never really got a chance to use them.
As always, it's part of the human nature to intentionally keep secrets well guarded from profane viewers.
And one of the best methods to do that and hide such treasures in plain sight has always been to use convoluted language to talk about mysteries of the universe.
Fortunately, that kind of stupid and preposterous shit only happens in fairy tales, am I right?
If you didn't get bored by my tale and are still here, then we can proceed to talk about these so called "closures".
But not in the way those snobs with their noses so high they fall the funniest when they trip down for looking up at the sky all the time instead of sometimes looking down at the ground when they walk, would talk about this topic.
Oh, no no... this was written from the point of view of a simple man that only wants to have a better masturbation toy... ahem... a better videogame; a better modded Skyrim.
