Interesting. For the record, that SRFI is David Wheeler's Sweet Expressions :) I feel like your use of the word "attempts" implies these ideas were unsuccessful, but I would disagree. Perhaps Lisp in general has not "succeeded" in that its original purpose (AI research) has entirely abandoned it, but I think the problem of low general-purpose adoption is overstated. In particular, since Lisp does not play nicely with the C calling convention, it's ability to integrate into polyglot systems has always been problematic, but I have confidence that the future will be better for FFI's in general, perhaps starting with WASM, which hopes to create a "universal ecosystem" of libraries (components). In theory, any program written in Lisp, or Rust, or Javascript, could import any package from PyPI by means of a WASM component. If this becomes reality, Lisp would be much more appealing to people currently put off by the languishing ecosystem and lack of integration, and may yet even have a fighting chance of reclaiming it's AI research credentials, simply by importing numpy :)
