Someone should write an arc interpreter and call it tan so we can have arctan. Arctan? Arctangent? The inverse of the tangent function. Hu- hullo? Is this thing on or what?

... or an interpreter named "tic" and then you can work in the arctic.

Isn't it like 6 years old? http://tryarc.org/ is also interesting; and somewhat more recent.

Better hurry, only 94 years left.

Will it run news.arc?

Atwood's Law alive and well.

Just tried it. Very nice!
