I am not against or in favour of it but just a question.

What would the results be for the following code? In ruby (I find
it easier to read ruby code rather than the description actually):


I'm not sure the description is that hard to read... Is the same as #first
but raises an exception of the enum doesn't have exactly one element.


    [].single
    [1].single
    [1,2].single
    [1,2,3].single


Err, 1, err, err


    {}.single
    {cat: 'Tom'}.single
    {cat: 'Tom', mouse: 'Jerry'}.single


Err, ['cat', 'Tom'], err


    (And any other Enumerable objects I may have forgotten here.)


Same as .to_a.single I suppose.

Cheers
