That's surprising. It even has a wikipedia page.
Given the fact that no new languages will ever succeed ever again due to the deletionism in wikipedia I've started making a list of languages everyone should have heard of:
dao, nimrod, pure, rust, factor, coffeescript, boo, scotch, ela, vala, ooc, x10, bitc, arc, newlisp, cobra, seed7, wirbel (no longer developed)
