Hi,

It's called a "splat". A variable at the end of the function call with an
asterisk at the start [or elsewhere in Ruby 1.9?] "takes the slack", as
such, and allows an indefinite number of extra arguments. For example:

>> def fun blah, *args
>>   puts "blah: #{blah.inspect}, args: #{args.inspect}"
>> end
=> nil
>> fun 1
blah: 1, args: []
=> nil
>> fun 1, 2
blah: 1, args: [2]
=> nil
>> fun 1, 2, 3
blah: 1, args: [2, 3]
=> nil
>>

Cheers,
Arlen.
