# I already have the fix; filing for records

If you try to write `else` with an `unless` clause, you get a nice error, telling you `unless` doesn't take `else` and you should rewrite with `if`

However, all other possible combination still talk about `unless` not taking `else` and suggest using `if`, even in cases where `if` would do a different thing​:
