One of the basic features missing in SharePoint 2007 has for me been the possibility of picking things up, taking them to another location, and dropping them into place. Be that files, folders, tasks or whatnot – I’ve wanted to pull them about. It’s no joke that file copy / move in default SharePoint is as fun as watching grass grow. Even with webdav, it’s nowhere near as pleasant as it should have been.

On the spot in this post is the lambda library. Simply put, a lambda here means an expression with placeholders for parameters to come. As such, it’s not unlike the closures we already have in javascript, but this does up the stakes a little bit.
