> gdb's language code may know how to display values specially.  For
> example, the Rust code understands that &str is a string-like type, or
> Ada knows how to handle unconstrained arrays.  This knowledge is
> exposed via val-print, and via varobj -- but currently not via DAP.
> 
> This patch adds some support code to let DAP also handle these cases,
> though in a somewhat more generic way.
> 
> Type.is_array_like and Value.to_array are added to make Python aware
> of the cases where gdb knows that a structure type is really
> "array-like".
> 
> Type.is_string_like is added to make Python aware of cases where gdb's
> language code knows that a type is string-like.
> 
> Unlike Value.string, these cases are handled by the type's language,
> rather than the current language.

Thanks, the documentation parts are okay.
