Foo::_fiddle has no relation to the Bar::_fiddle method and the similarity of names is a coincidence. Unfortunately, calling the Foo::wonk method via an instance of Bar will still call the Bar::_fiddle method, even though this may not be desireable behavior. Not having clean encapsulation of private methods makes this very difficult to get around. You could try to get around it like this:
# in package Foo
sub wonk {
my $self = shift;
_fiddle($self, @_);
}
I'd prefer to write that $self->Foo::_fiddle,
even though it would be slower.
That looks better, but if the private method violates encapsulation and reaches into the object (a common practice), it might be making assumptions about what's there, even if those assumptions are not warranted.
Don't understand what problem/assumptions you see as
problematic here. Can you elaborate?
I don't think I would use delegation for private methods; it feels like using a wrench to unscrew a lightbulb.

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).
