I couldn't agree more. (hence the ++). Remember, it may not just be newbies - but for those of us for whom Perl programming is not 100% of our job, we cannot know all about every module.

Sometimes, an explanation like "The module Foo::Bar is what you need - is has some methods that are ideal for dealing with n-dimensional matricies.". It also soften's your response a little - and may reduce the possibility of "personality down-votes"
