I can usually read JS generated by TS, but calling the C Nim outputs "human-readable" is very generous considering it flattens most structured control flow to goto. (It's hard to do it otherwise, Nim has to deal with exceptions and destructors but C has neither.)

Classifying Nim as a transpiler also results in weird cases like NLVM[1] which most would consider a compiler even though it is a back-end on the same "level" as Nim's C generator.
