We are also pursuing generating Curl with a few selected Smalltalk web frameworks: HttpView2 for Squeak Smalltalk and Iliad for Gnu Smalltalk in addition to Seaside in Pharo Smalltalk. Once Dolphin Smalltalk has migrated to Lesser, we may return to Dolphin as a preferred Smalltalk dialect.
One of the lesser known languages suitable for the task is ICON (available as ICON, UNICON, ObjectIcon and Converge.) WE are also following closely the evolution of Rebol 3 at http://www.rebol.net and Io at http://www.ioloanguage.com
Perhaps the most flexible language available is Oz.
