Its not inconsistnet at all if you understand what the semantic are
rather than what you think they "ought" to be.
What do you get if you do:
print join(" ", @array[0,1,2,2,1,0]), "\n"; ?
You are not accessing an array element but rather an array slice.
The stuff between the [] becomes the list of elements that are to
be returned.
