How about making it all explicit, put $foo in its own package, and just be judicious in your use of the full name of $foo.

#!/usr/bin/perl -w use strict; package Foo; use vars qw/$foo/; $foo = "bar"; package main; # always use $Foo::foo from here on down

Or you could exploit the fact that my variables scope, while it stretches across packages declared in the same file, does not reach outside of the *file* in which they are declared. I.e. if in foo.pl you declare $foo with my, then that variable won't be visible inside subroutines declared in bar.pl

A little more souped-up kind of idea might be to define an *object* with accessor methods. Syntactically annoying (which I gather is what you're trying to avoid =), but IMO, conceptually quite clean.

final note: please, use a more descriptive title ... it might help others trying to solve the same problem =)

Title:
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.
