Here's another for you: Lilith. Assembly is messy. So, they create a stack machine (M-code - P-code variant) that idealizes it plus easily compiles to it or implementable at CPU level. Then, they create a 3GL called Modula-2 that's closer to how they express programs but has underlying model of M-code and outputs M-code. In theory, they could go further like 4GL's did to build domain-specific languages that abstract away boiler plate with code generation but still consistent with Modula-2 style. And so on. Easier in functional languages but I'm sure you can see the pattern.
That's what you usually get out of the DSL or interpreter approaches if using a LISP, Haskell, or imperative language designed to make it easy. Languages designed to do them well. A series of transforms with a certain amount of consistency from start to finish. These days, there's even safety techniques for the transforms that they didn't have way back in the day. :)
