In 2001, Paul Graham announced that he was working on a new dialect of Lisp named Arc. Over the years since, he has written several essays describing features or goals of the language, and some internal projects at Graham’s startup business incubator named Y Combinator have been written in Arc, most notably the Hacker News web forum and news aggregator program. Arc is written in Racket.[2]

In the essay Being Popular[3] Graham describes a few of his goals for the language. While many of the goals are very general (“Arc should be hackable”, “there should be good libraries”), he did give some specifics. For example, he believes it important for a language to be terse:

It would not be far from the truth to say that a hacker about to write a program decides what language to use, at least subconsciously, based on the total number of characters he’ll have to type. If this isn’t precisely how hackers think, a language designer would do well to act as if it were.
