in reply to To Kill a Meme: while(defined($line = <>))

Huh. I've never seen that line. I guess it means that I'm a relative Perl newbie, huh? (The first version of Perl that I seriously used was 5.6, though there was some very minor dabbling with Perl 4-something)

All of my file readings that use while loops pretty much use the syntax while(chomp($line = <FH>)) already...

    while(chomp($line = <FH>))

    This is probably a more dangerous meme than while($line = <>) ever was—if your file is missing a terminal linefeed (or CRLF, as the case may be) you'll skip the last line. Not a common failing of text files, but all you need is one for it to bite you, hard.

      Huh. Learn something new every day. Thanks for the heads up.

    You aren't by any chance the author of the Perl books that are in use by HP-Education, are you? For a long time I thought that the Perl books SUN-Education made were the worst Perl books ever made, but then I got to see the HP books, full of gems like while(chomp($line = <FH>).

      Nope, no authorship here. Especially not for anything on Perl.

      And while I can't say that I am really happy to have provided an example of a "gem" that you think is the worst Perl ever, I do appreciate knowing that this isn't the prescribed way to do things. I've never had this bite me, but it's good to know that it has big teeth.
