[Templates] Lists and rand like http://faq.perl.org/perlfaq4.html#How_do_I_select_a_ra

[Gavin Henry]

Dear all,

I am trying to get a random image/"Tip of the Day" from a list of
images/tips for one of our sites. I was playing naively with:

[% USE Math %]

[% tips = [ 'test'

              'test1'

              'test2'

              'test3' ] %]

[% Math.rand(tips) %]

But in my eyes tips is an array ref, so it will be using the memory
address of that array and giving me a random fractional number greater
than or equal to 0 and less than the value of this address.

What's the proper way ;-)

Cheers,

Gavin.
