This is one of those examples of things that bothers people, myself included. Three shifts, and no use of @_ to justify it, really. Instead, you could just declare them in a single my and be done with it, like:
my ($obj, $usr_log_file, $params) = @_;
Extra params passed by the user are discarded, as one would expect.

The reason being shifty is annoying is because it can degenerate into nonsensical situations like this:
sub foo { my $self = shift; my $foo = shift; $self->something($foo, "bar", shift, "shift", "foo"); my ($flob,$blarg,$kvetch) = (shift,shift); if ($kvetch = $flob->fnordicate($blarg)) { shift()->refnordicate($kvetch); } }
What, exactly, are the parameters to this function? You have to read and understand the entire function before it becomes clear. If this were much larger, that could be very frustrating. Unfortunately, this fictional example is not too far fetched.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
