Lemme re-comment this for you:
use strict; sub This::Does::Not::Fail { }; # Rightly so because you've already notified Perl that # this is a subroutine name. It *knows* this identifier # is a sub. Thanks for pre-declaring it! This::Does::Not::Fail; # rightly so # This fails because you've given perl no contextual hints # that this is a subroutine. It might be... a filehandle! # Or something else. But you haven't pre-declared it # either. This is a bareword (an identifier). This::Will::Fail; # as we expect # You haven't pre-declared this thing. # *BUT* you did give perl a contextual hint that this is # indeed a subroutine. This is essentially a *promise* # you've made to strict that at runtime, when this code is # encountered, you'll have a subroutine with this name # all ready to go. It::Bothers::Me::That::This::Works (); # wassup with THAT?!
For that last point, there are other "promises" you can make and not just with parens. Some of these include:
$obj->method; # Either $obj class' method will exist or # AUTOLOAD had better take care of it later. $a=foo Bar; # Bar will have a foo()! Or AUTOLOAD...etc. &foo; # Again, you've promised it will exist...

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 How to display code and escape characters are good places to start.
