Respectfully disagree. DSLs embedded into another language are doubly terrible. Independent DSLs like GLSL or SQL are tricky to get right, but work; but they're just their own languages.

With embedded DSLs you don't get the portability of a library and reusability of a library, but instead get a horribly crooked, compromised, limited grammar based on the meta-programming limitations of the hosting language (looking at you gradle!).
