Use of expression templates in C++ to implement DSLs is probably some of the most awful code ever conceived.
Whereas string mixins allow us to do all kinds of crazy stuff with DSLs if you want to - but they're clearly confined in strings where you're not going to mistake them for normal D code. It's _very_ cool how Pegged is able to take a grammar in normal, PEG format, and generate a parser from it. But attempting anything like that with expression templates would have been horrible.
