( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Though I share merlyn's reservations about the idea in general, I think it's worth pointing out that the OP's aliasing method doesn't break inheritance, but this one does: if a subclass overrides the main spelling of the method, the alternate spellings should also be directed to the overridden method, rather than bypassing it. As an alternative approach that combines something approaching safety with reasonable typing economy, I'd try something like this:

_make_aliases('real_method',qw(foo bar baz blort)); sub _make_aliases { no strict 'refs'; my ($main_spelling,@alternates) = @_; foreach my $new_method (@alternates) { *{$new_method} = sub { my $self = shift; $self->$main_spelling +(@_) } } }

This approach should (I haven't tested) let subclasses safely ignore the aliasing entirely, and just override the main method—though any diagnostic messages may still be a bit confusing. And it still provides the economy of keystrokes that the OP was looking for.

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.
