/**
* Autoloader checking if the class is really defined in the file found.
*
* The ClassLoader will wrap all registered autoloaders
* and will throw an exception if a file is found but does
* not declare the class.
*
* It can also patch classes to turn docblocks into actual return types.
* This behavior is controlled by the SYMFONY_PATCH_TYPE_DECLARATIONS env var,
* which is a url-encoded array with the follow parameters:
* - "force": any value enables deprecation notices - can be any of:
* - "docblock" to patch only docblock annotations
* - "object" to turn union types to the "object" type when possible (not recommended)
* - "1" to add all possible return types including magic methods
* - "0" to add possible return types excluding magic methods
* - "php": the target version of PHP - e.g. "7.1" doesn't generate "object" types
* - "deprecations": "1" to trigger a deprecation notice when a child class misses a
* return type while the parent declares an "@return" annotation
*
* Note that patching doesn't care about any coding style so you'd better to run
* php-cs-fixer after, with rules "phpdoc_trim_consecutive_blank_line_separation"
* and "no_superfluous_phpdoc_tags" enabled typically.
