When introduced in the early 1990s, Borland's Delphi application development environment targeted Windows only. With Kylix, however, Borland (the company we work for) has brought the Delphi toolset and environment to Linux. As with Delphi, Object Pascal is at the heart of Kylix. Consequently, in bringing Delphi to Linux we first had to port Object Pascal and all of its language features. And, as it turns out, one of the most challenging features to port involved exception handling.
