There was a problem hiding this comment.
dylib here is important but easy to miss, can we add some comment around crate-type explaining it? Or we can rename bar to my-dylib and baz to my-proc-macro.

I meant explaining why we are testing against dylib not rlibs or others.

Its important for dylibs but also applies to rlibs as well.
In hindsight, I probably should have been testing both.
I updated the test include both rlib and dylib deps to the proc-macro. Also updated the crate names to make it more clear.
lmk what you think :)
