Safe sandbox: Rebol had Protect and Secure dialects [1, 2], which are planned to be implemented in Red. Language is very dynamic though, so there's a certain limit on what kind of safety can be enforced at runtime. Creative problem domain: that's what Red is all about in my point of view - slapping domain-specific languages one on top of another to pin down the exact problem space. Draw for 2d vector drawing, View for GUIs, Parse for, well, parsing and metaprogramming, et cetera. The crux is usage of same data format and common notation at every abstraction layer, be it low-level programming or high-level scripting. I don't think that Red can handle large-scale projects the way language workbenches do (yet), but it can be used for moderately small embedded DSLs. Does that answer your question?
