in reply to Exists and arrays

from perldoc -f exists: Given an expression that specifies a hash element or array element, returns true if the specified element in the hash or array has ever been initialized, even if the corresponding value is undefined.

My perl behaves the same way

This is perl, v5.8.8 built for i486-linux-gnu-thread-multi
