Well, they mess up the #! line at the start, but otherwise perl ignores them,
in my experience.:w
But the *aren't* normally present in "ordinary" edited files, like perl
scripts; they *are* normally present in typescript files; and one normally
*does* strip them when getting files from MS-DOS; if you FTP them in text
mode, then this will normally be done for you; otherwise numerous tools can
strip them for you.
But this is all normal, run-of-the-mill Unix behavior.
