[TYPO3-core] Double backslash for namespace

[Bernhard Kraft]

Hi !

I would like to ask if it is really necessary (according to the CGL) to 
have double backslash in namespaces. Whenever the single quote string 
style is used it is not necessary regarding PHP syntax.

So:

$someObject = GeneralUtility::makeInstance('TYPO3\CMS\SomeObject');

Would be fully valid. Double backslashes are not required. I guess they 
were introduced because the "\" operator is known to be the escape 
operator. But in case it is followed by any non-escape character it 
won't do anything. Only if combined with special meaning characters like 
"\n", "\r", "\x" they will get interpreted - and this also only in 
double quoted strings.

So if we stick to single-quoted strings as usual in TYPO3 world it would 
be ok to have only one backslash.


greetings,
Bernhard
