There are also a whole bunch of languages for:

- Describing levels in video games, which are primarily data with code mixed in

- Describing transformations of different sorts (e.g. the types of languages used in compilers for specifying a programming language parser, and then optimizations)

- Defining hardware (analogues to Spice, Verilog, and VHDL). Hardware can also include mechanical objects, as well more broadly, wetware (e.g. custom bacteria, a la Ginko Bioworks)

- Run on custom hardware (e.g. SIMD and MIMD platforms, similar to GPGPU)

- Are primarily mathematical (e.g. for describing control systems, neural network architectures, etc.)

... and so on.

Not all of this is a DOD/medical mess. A lot of DSLs are REALLY REALLY FUN.
