Can not get the span of Mutability from ast #78315
Description
Currently we can not get the span of mut keyword.
Example:-
fn foo(file:`& /* Some comment */ mut /* Another Comment */ File`) {}I like to work on this issue. But I need an advice. If I store the span in an enum field like Mutability::Mut(Span) I can not implement the invert function.
