Hello all,
I've posted a small update to Sleep 2.1.  This update fixes some  
minor bugs:

2.1-release  (1 Jul 08)
===========
- splice() no longer corrupts sublists.
- values(%hash) now omits $null values.
- sped up scope functions: &local, &global, and &this by cacheing
   the regex pattern used to split up the var names
- added a compile time check for %(a => ... b => ...) errors
   [notice the missing comma between the key/value pairs]

The release is available at http://sleep.dashnine.org/
