Good point. I'll address that in v3.

Yes, this was the primary and only motivation. <*, id> is much clearer and I'm with you on finding a better alternative.

I think this is better than just obj, but in my opinion this may be confusing for readers and look like a typo. I think I prefer your second suggestion, though obj really makes more sense in the case where we're actually passing an @obj to the function. I'll probably (deservedly?) get lambasted for suggesting this, but what about taking a page out of rust's book and doing something like this:
* klp_shadow_free_all() - detach and free all <_, id> shadow variables * with the given @id.
to indicate that in this case we don't care about the obj. Even for a reader unfamiliar with rust, hopefully it would get the point across.

I'm fine with this as well. Let me know what you think about <_, id> vs. what you suggested, and I'll send out the v3 patch with your preference.

Indeed you're correct. There's no warning in the build system because there happen to be two <*, id> ... <*, id> in a row, so rst happily italicizes what's between them without question. I'll fix this in the v3 of the patch as well.

Thanks for taking a look and for the helpful suggestions.
