Yeah, I found it odd that it threw that warning without warnings turned on, but it still works; I wonder if that is a bug. Adding the parenthesis (and dropping the + since it is no longer needed to prevent (33..126) from looking like the arguments to chr) only adds one more character: perl -le'print map chr((33..126)[rand 94]),1..8' Also, the more confusing variant: perl -le'print+map+chr((33..126)[rand 94]),1..8' -- Chas.
