After 2 years of development, Sleep 2.1 is now released. Sleep is a Java-based scripting language heavily inspired by Perl. Features include first-class functions and continuations, a built-in debugger, taint mode security, and access to the Java class library. Sleep embeds into applications, executes scripts stand-alone, and it supports the Java 6 Scripting Framework.
