in reply to breaking long code lines

That's not really a Perl-issue, but more of a Tk-issue.

More generally, I think it mostly depends on the editor you are using. Some editors allow indeed for "line continuation codes" or do the word-wrap thing automatically. KOMODO comes to mind in this respect.
