Code Inspection: Unnecessary leading '\' in 'use' statement
use statements with an unnecessary leading
For namespaced names (fully qualified namespace names containing a namespace separator, such as
Foo\Bar as opposed to global names that do not, such as
FooBar), the leading backslash is unnecessary and not recommended, as import names must be fully qualified and are not processed relative to the current namespace.
See Using namespaces: Aliasing/Importing (php.net) for details.
