Returns a variable from the context.

This method is for internal use only and should never be called
directly.

This method should not be overridden in a sub-class as this is an
implementation detail that has been introduced to optimize variable
access for versions of PHP before 5.4. This is not a way to override
the way to get a variable value.

@param array  $context           The context
@param string $item              The variable to return from the context
@param bool   $ignoreStrictCheck Whether to ignore the strict variable check or not

@return mixed The content of the context variable

@throws Twig_Error_Runtime if the variable does not exist and Twig is running in strict mode
