[Syntax rule] Use an explicit access modifier on each method In the past the menu item of AOT > Classes > MyClass > New Method created the method without any access modifier. This meant that the method was implicitly public, although some X++ developers might not have been fully aware of the default. This created extra work later when a developer needed to modify the code in the method, because the developer had to research everywhere that the method might be called from. Now the New Method menu item explicitly includes the private keyword in its automatic declaration of the new method. The developer can type in a different modifier if appropriate.
