Maybe this could be "location for crate {} is not a file: {}" using self.crate_name.

I formatted this error like the other ones in the closure. Should those be changed as well?

Oh, I see. Changing them to include the crate name would make them more informative.

… r=Veykril fix: Don't add reference when it isn't needed for the "Extract variable" assist I.e. don't generate `let var_name = &foo()`. Because it always irritates me when I need to fix that. Anything that creates a new value don't need a reference. That excludes mostly field accesses and indexing. I had a thought that we can also not generate a reference for fields and indexing as long as the type is `Copy`, but sometimes people impl `Copy` even when they don't want to copy the values (e.g. a large type), so I didn't do that.
