-   Objects do not inherit from Printable because it is a virtual base class.
-
-   Therefore, statements like ``Serial.println(myDoubleArray)`` are not supported.
-
-   This also avoids ambiguity between implicit WString conversions.
-
-There are some Print helper functions in the library you can use::
-
-   FSTR::println(Serial, myDoubleArray);
-
-These are templated so will handle both simple data types and Objects.

 You can share Arrays between translation units by declaring it in a header::
 
    DECLARE_FSTR_ARRAY(table);
