Sleep is a Perl-inspired scripting language for the Java platform. Sleep has its own library of functions for performing common tasks as well as being able to utilize the Java class library. Sleep includes closures, coroutines, built-in debugging, and it is very extensible.

Changes

Read-only hashes and arrays now fire a warning when a side effect op is attempted. An inconsistent error handling bug in profile only debug mode was fixed. $null now evaluates to null and not "" when passed to Java as a String. The fork() function now places useful information in the created thread name.
