I prefer just use (eval '...) in those cases where the expansion fails.
That way the file is more readable, and a reader focus her eye in those
failing expansions.
Maybe we could add a comment in the file saying that those
`should-error' are failing expansions to be fixed.

That's great! Looking forward to see the patch fixing these problems.

Sure, as long as the errors are expected.
