in thread How can I make a string unique (quicker than my approach at least)

Agreed.

Curiously, in this case the top answer at StackOverflow points to the identical faq link you pointed to ... while the second top answer cites perldoc -q duplicate (which emits identical content) and then further goes to the bother of embedding verbatim brian_d_foy's excellent FAQ entry in the SO response! ... so you'd think harangzsolt33 must have seen it (or requires a new pair of glasses) ... maybe he can comment further to clear up this mystery. :)
