So, I think it would be real helpful to have some other funky string quote like****
##{{ }}## or some sequence that is very unlikely to occur in another language.****

Has anyone done this or even thought about it?
David Leibs has been pushing a well-thought-through facility he calls (and other systems name) "quasi-quote". Here, a string literal contains escape sequences, a little like printf, that allow one to substitute values. Dave's syntax uses square brackets to escape into Smalltalk. So that (IIRC) you say things like '<html><head></head><body><H1>[myHeading]</H1>' which compiles to something analogous to String streamContents: [:s| s nextPutAll: '<html><head></head><body><H1>'; nextPutAll: myHeading asString; nextPutAll: '</H1>] But this excellent suggestion has fallen on deaf ears (my own included) for more than a decade. ****
