The code posted above includes the following lines:

 my @First=split /\./,$a||shift;
 my @Second=split /\./,$b||shift;
 foreach(0..(($#First>$#Second)?$#Second:$#First))

Could anyone explain to me what the # in the variable name does?

The Llama and Camel books describe how # can be used for comments, formats and the shebang execute command. But in this code # affixed to the name of an array appears to be neither a comment or a format or a shebang. # affixed to the start of an array name automagically become — well, I don't know what it becomes.

Does anybody know?
