I have nothing specific in mind, I’m just brainstorming with everyone
here.  :-)

For a similar situation in C++, there’s a fairly simple and local
workaround:

  https://issues.guix.info/issue/30265#8

I’m not familiar with CL but I thought that it we could achieve
something similar, that would be great—I’m not suggesting to change the
CL compilers in any non-trivial way.

For example I guess we could always store the file name as a literal
byte vector/list and add a call to turn that into a string.

Does that make sense?

Thanks,
Ludo’.
