I'm not sure what a join can do that's dangerous. Many ! methods change their receivers, but you can't change an array object into a string object. David -- David A.

> you can't change an array object into a string object With all these one_line_that_does_billions_of_things methods in ruby i tried to reuse my array variable to store a string, so i won't have to introduce new variable. I forgot that it will be different object :)
