It seems one of the first file formats that embed WebAssembly modules. Is there any other prior work? I'm specifically interested from the compression perspective as a well-chosen WebAssembly preprocessor can greatly boost the compression ratio. (In fact, I'm currently working on such file format just in case.)
Alan Kay described [1] what he considers the first object oriented system, made in the 60s by an unknown programmer. It was a tape-based storage system, where the "format" of the tap was a set of routines to read, write, etc. at a known offsets on the tape.
