note extremely <p>The short form of [merlyn]'s answer is "use with impunity" =) <p>His point was that the "use Xxxx" happens during the "compile" stage, before the code begins to run. See [id://751|use vs. require] and [use] are helpful. <p>Oddly, the opposite topic came up just a week ago or so. Someone wanted to know HOW to make a "use" not happen at compile time. Here is one post from May [id://15239] and the post from Oct 9, [id://35940]. <p>Hope that helps... <p><i>-- <br> $you = new YOU;<br> honk() if $you->love(perl)</i> 36600 36600
