stackedit.io/app#

stackedit.io/app# seems to me to be the sort of rich web app that MIT Curl, of Curl.com, intended to be back 20 years ago as an alternative to HTML+CSS+JS as a declarative web content language already equivalent to JSON  as a homoiconic data declaration language ... not quite Rebol 2.7.6 or a Smalltalk or Visual Prolog, but having worked in both Smalltalk and Prolog dialects, i can say it was as strong as VisualAge Smalltalk, Visualworks Smalltalk and now opensourced  Dolphin Smalltalk for Windows. Comparing Visual Prolog to Smalltalk is not quite fair ... Comparing new Mercury to old Strongtalk m8ght be closer to being fair ?
