in reply to GetOpt::Long usage style
Under the general heading of 'ever so slightly embarrassing' I would admit to having to stick opt_ as a prefix to my GetOpt::Long variables---I attribute this to too many years as a machine code morlock (i.e. too many globals) That aside I like your reasoning and results, will adopt forthwith!!
