In this sort of scenarios, localize the use of required extensions and Management their use with non-Main Coding Tips. their website If at all possible, Establish interfaces that encapsulate the extensions so they can be turned off or compiled away on units that don't assistance These extensions.
We don't limit our comment while in why not check here the Enforcement sections to issues we understand how to enforce; some opinions are mere wishes Which may encourage some Instrument builder.
