  - asEnumerable
```
public Enumerable<T> asEnumerable()
```
    Description copied from interface: ExtendedEnumerable
    
    Returns the input typed as Enumerable<TSource>.
    This method has no effect other than to change the compile-time type of source from a type that implements Enumerable<TSource> to Enumerable<TSource> itself.
    asEnumerable<TSource>(Enumerable<TSource>) can be used to choose between query implementations when a sequence implements Enumerable<TSource> but also has a different set of public query methods available. For example, given a generic class Table that implements Enumerable<TSource> and has its own methods such as where, select, and selectMany, a call to where would invoke the public where method of Table. A Table type that represents a database table could have a where method that takes the predicate argument as an expression tree and converts the tree to SQL for remote execution. If remote execution is not desired, for example because the predicate invokes a local method, the asEnumerable<TSource> method can be used to hide the custom methods and instead make the standard query operators available.

```
    Description copied from interface: ExtendedEnumerable
    
    Converts the elements of this Enumerable to the specified type.
    This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its RawEnumerable.enumerator() method directly or by using for (... in ...).
    If an element cannot be cast to type TResult, the Enumerator.current() method will throw a ClassCastException a exception when the element it accessed. To obtain only those elements that can be cast to type TResult, use the ExtendedEnumerable.ofType(Class) method instead.
