It appears that the next version of Delphi will support a feature called anonymous methods. The circumstances in which one might use an anonymous method do not seem to be obvious to everyone in the Delphi community, so I’m going to attempt to answer that.

It seems that the popular screen reader (software which translates text on the computer screen into spoken audio for the blind) JAWS has problems with applications produced in Delphi when they are manifested for Windows XP.
