 this change consistently should not be hard.  Still, it's not very
 important, so I think I'll milestone it for 6.10, not 6.8.

 If this is the right way to solve it then I can try to do it. But if there
 are a
 lot assumptions throughout the compiler that `Sig` refers to only one
 `name`
 then is it still worth it..? (I can imagine that such a change might
 unnecessarily complicate some things)
