top-level tools for ActionScript 3
Top-Level Tools is a collection of package-level functions to make your ActionScript 3 life easier.
Package-level functions are slightly faster than static function calls and more convenient from your IDE as they're available anywhere with auto-complete. I initially considered building runnable classes with interfaces for each of these functions for best "out-of-the-box" performance, but decided it's just best for you to copy/paste these functions inline if you're seeking the best possible performance from these. (Considering starting an MXMLC ticket for supporting inlining to solve this problem completely)
A large part of the project is focusing on gathering utils from other open-source projects around the web. The list below deserves the proper credit for writing these great utils: http://casalib.org/ http://code.google.com/p/sekati/ http://code.google.com/p/as3-commons/ http://jacksondunstan.com/ http://blog.soulwire.co.uk/ http://www.flightxd.com/flightframework/ http://destroytoday.com http://code.google.com/p/as3corelib/ http://code.google.com/p/copyengine/ http://www.senocular.com/flash/actionscript/?file=ActionScript_3.0/ more to come...
