And what's the solution, for you? Using strings as DSL is somewhat common in D.

As for DSL, well, I have a parser generator project here
(https://github.com/PhilippeSigaud/Pegged), and I recently added the
capacity to add new rules to a grammar at runtime and modify the
resulting parse tree. I also used the existent, but unused macro
keyword in D to get source code that can define its own subsequent
grammar and parse tree transformations.
Oh, and grammars can call one another, so adding a new sublanguage to
a parent language is doable (I use this from time to time). I still
have weeks fo work on this to have it reach the level I want, but I
did not hit any wall up to now.
So adding clean-looking DSL can be done in D, I think.

No, indeed :) Since it's a recurring question here, I just showed it
could be done. It's also a simple example of what can be done with D
meta-programming capacities.
