@pikesley the real thing that made it nice was that DSLs were an up-front goal (they called it dialecting.)

code stayed as a bag of symbols unless you evaluated it. you were intended to use this so you could just read parsed code like an array of things and use that to write your own job specific interpreters.

they never got a whole lot of those for various reasons. the draw dialect was meant to be a proof of concept.

in a way its like Lisp macros
