I think I must be misunderstood you then. No problem. But would you
agree that gil and fusion share at some code which could be
eliminated?

It's fine when you just point out the general idea. What algorithms in
fusion do you use that's not available in gil?

So there is no way to define the return type for reverse view?

Could you hint me some ideas for what fusion provides that's not in gil?
