Hmm, the ideal solution would have been if YAML supported some kind of
range definition, but I can't see anything like that in the spec.

This looks something that would be quite common - so I've added the
functionality to the group element (which select is a sub-class of).

There's a new value_range() method, which works like values(), but
expects an array-ref of at least 2 values.
So, this YAML is equivalent to the following perl code:

    ---
    element:
        type: select
        name: year
        value_range: [1900, 2000]

    $form->element({
        type => 'select',
        name => 'year',
        values => [ 1900 .. 2000 ],
    });

and with more than 2 values:

    ---
    element:
        type: select
        name: year
        value_range: [year, 1900, 2000]

    $form->element({
        type => 'select',
        name => 'year',
        values => [ 'year', 1900 .. 2000 ],
    });

You'll have to update from svn to get these changes.

Cheers,
