Is there any evil in using a var/ary/hash over and over again? Example:
You slurp several text files in, one at a time. For each file, you use DATA as a file handle, and you put the contents of the file into @lines.
It will work, but are there any side effects of using the @lines array for many different data sets in the same script? What about $variables and %hashes? Or, is this the perferred method for memory conservation?
