Description
In the rust book section on mutability the text is written in a very confusing way. I'm particularly thinking of the bits of text like:
when we say something is ‘immutable’ [...] we mean something has ‘exterior mutability’
Perhaps this can be reworded as:
when we say something is ‘immutable’ [...] we mean something has ‘exterior immutability’
Or if the phrase "exterior immutability" isn't acceptable, then a more general rewording like:
when we say something is ‘immutable’ [...] we are referring to its ‘exterior mutability’
Or:
when we say something is ‘immutable’ [...] we mean something has ‘exterior mutability’ that in this case is immutable
As it's currently worded it sounds roughly like saying "when something is immutable it is mutable", since saying that something has "exterior mutability" sounds like saying it is mutable on the exterior.
