I came across this Tcl advocacy article on Reddit (the article is from 2006):

"Everything is a string" concept of Tcl reminded me of how D can generate code as string. So, Tcl's 'uplevel' is like string mixins. It's also similar to how body of 'static if' is inserted into this context.

Hmm interesting I had not thought of it that way. Since  Tcl's Uplevel executes a script in a different stack frame / scope to the current executing code in Tcl and returns the result so i always thought string mixin's are more of a compile time eval rather than Uplevel. Seeing your post and  thinking on it - i can see why you made the connection and both are very useful in their respective languages.

Since i code in both Tcl and D - nice to see a connection here.
