This first call to bob uses a map in void context whereas the second call does not. The point was to imply the question of whether I should use two different subs to perform the same task having only the difference that one returns a list and the other returns nothing.

bunnyman: [In response to: And why then is map allowed to be called in void context?] There are a lot of things you can do with Perl that you shouldn't do.

Following that logic, I should create two subs. Perl takes the stance of TIMTOWTDI. Why not let the programmer determine what should be used instead of laying down a draconian policy?

dash2, this isn't directed towards you (considering we are basically on the same platform with this one). I'm just saying what I thought was obviously implied by the code.
