It seems that the author of the question wants symantics that are like chop. People know what chop is going to do to their variable. If the user is well aware of the way the subroutine will work, is it all that bad? Since you would have to do that with chop anyway?

Just one guy making conversation with someone who's been coding for 30+ years (honest). {grin}
