Nim macros are extremely useful for assemblers and emulators as contrary to many codebases which needs to use an intermediate code generation step via text files [1][2][3] you can directly use them with type checking and all Nim facilities while keeping an easy to read syntax: https://github.com/numforge/laser/blob/e898f027/laser/photon...
I'm playing a lot with VM, interpreters, JIT and recently compilers in Nim.
Here is a JIT brainfuck VM: https://github.com/mratsim/jitterland
