Hi,

In the guix codebase, on many occasions there appear things like this:

flow-control?

keep-baud? timeout

This has officially been Bad Practice for a while. Instead, the
recommended approach is to use ‘match-record’ from (guix records).
There are examples of that primarily in (gnu services …).
Does that help?
Thanks,
Ludo’.
I suppose It makes sense that one would want to be explicit about names
in a source code file.
BTW, if that is the recommended way, would someone with an understanding
of the records.scm code mind adding support for delayed & thunked fields
in match-record? There is a TODO there. I wouldn't know how to do it.
