I like -l but wish that there was a way to selectively counter-act it, as I occasionally (but not often) want to print a newline-less line. How do you handle these situations?

Localize $\.

$\ = "\n";  # as perl -l
print "before";
{
    local $\;
    print "continued";
}
print "after";
print "heh!";
[download]

which prints

before
continuedafter
heh!

In fact, you can set $\ to anything, and with local, it's safe — or at least, as safe as using $\.

IMO, every module that uses print in a hidden fashion, should use

  local $\;
[download]

and not rely on $\ being empty at the time its functions are called.

Note that printf ignores the settings of $\.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
