> there is nothing like the RAD interface Lazarus and Delphi have in the open source lisp world.
The key phrase there is 'open source' I believe, because tools like Lazarus come out of a pretty distinct Borland / Windows culture of making bespoke usually paid graphical development tools. Lisps have a lot of their roots in the academic and Unix culture with a lot of folks seemingly allergic to GUIs to this day. There's an interesting interview with Carmack from a year or two ago talking about this.
