A general Joomla! coding question... Checking _JEXEC is defined.

In administrator/components/.../src/everywhere it is

defined('_JEXEC') or die;
use function defined;

Whereas in components/.../src/everywhere it's

\defined('_JEXEC') or die;

Is there a specific coding standard that we should use for Joomla! code?

I asked this on the Joomla! internal development chat and was told the second one is the optimised version currently in namespaced files.

Richard, a lead Joomla! developer wrote "Backslash makes it clear it is looked for in the global namespace so less risk for name conflict and also a small optimization".

Benjamin, another lead developer wrote "from 7.0+ it then uses opcodes, which is the optimization, so most likely you should go for it also in non-namespaced files"
