> add each number in a list x to each number in the corresponding row of a two-dimensional array y

I mean, I could write a function `add(x, y)` that does that in any language. You could even inspect the data or type to make it polymorphic. I believe NumPy does this, for example.

Skimming the rest of the article, I don't get how this is different from any other language. The primary difference seems to be the function names are all one or two characters long for some reason. I must be missing something...
