Well, in fact, this is the only way to 'really concatenate'
two arrays (which is extremely useful if you have an existing
hash and just want to add a key/value pair at the beginning
or at the end). array_merge() can't help you and right now I
couldn't find any other array_*() function which helped me.
And I'm certainly not interested in writing a while(.. each()
construct or so or re-create a new array.
