r�Yn0|S)a�Get symbol by qualified name.

    The name should be the full dot-separated path to the class::

        modulename.ClassName

    Example::

        celery.concurrency.processes.TaskPool
                                    ^- class name

    or using ':' to separate module and symbol::

        celery.concurrency.processes:TaskPool

    If `aliases` is provided, a dict containing short name/long name
    mappings, the name is looked up in the aliases first.

    Examples
    --------
        >>> symbol_by_name('celery.concurrency.processes.TaskPool')
        <class 'celery.concurrency.processes.TaskPool'>

        >>> symbol_by_name('default', {
        ...     'default': 'celery.concurrency.processes.TaskPool'})
        <class 'celery.concurrency.processes.TaskPool'>

        # Does not try to look up non-string names.
        >>> from celery.concurrency.processes import TaskPool
        >>> symbol_by_name(TaskPool) is TaskPool
        True
