Agreed, that's a good idea.
At the moment similar mechanisms are:
- Declare a function with (declare (speed -1)) will include the
function in the .eln but in byte-code form.
- Have comp-speed to -1 as file variable in the source file should
produce an eln containing only byte-code functions.
But yeah, a dedicated cookie is better because there's no point of
producing the .eln file at all for cases like this.
