The implicit this-reference parameter is just that - another 
parameter. Any type constructor/qualifier can be applied to it, 
as with other parameters. Yes, you can rely on the behaviour. Use 
of `inout` on the this-reference is one of the most common uses 
of `inout`, as warranted by the popularity of member functions.

It is technically part of the documentation[1], but I agree that 
this use case should probably be included in the description of 
`inout`.
