Barely important for me but I use DSLs (for example to generate html) which wouldn't be possible to implement and change that easily for my usecase.

One important property for me is that the DSL used is implemented in the language it is being used from and modifiable at run time. Mathematica does the embeds stuff really well but I find it hard to work with.

Mixing DSLs is hard or close to impossible in Lisp though. I had better experiences in Julia in that regard.
