To build on [Ultra]'s [id://521862|reply], it <em>may</em> be a directive for a text editor. For example my editor, [http://www.jedsoft.org/jed/|JED], opens in <c>perl mode</c> based on extension (<c>.pl</c>) and/or shebang line. But for my modules I did not set up an association. I always put a
<c>
# -*- Perl -*-
</c>
comment at the top of them instead.
