Vigil, the eternal morally vigilant programming language

> This is where Vigil sets itself apart from weaker languages that lack the courage of their convictions. When a Vigil program is executed, Vigil itself will monitor all oaths (implorations and swears) that have been made. If an oath is broken, the offending function (the caller in the case of implore and the callee in the case of swear) will be duly punished.

> How?

> Simple: it will be deleted from your source code.

> The only way to ensure your program meets its requirements is to absolutely forbid code that fails to do so. With Vigil, this shall be done for you automatically. After enough runs, Vigil promises that all remaining code meets its oaths.
