Re^5: Use method/function signatures with Perlby Juerd (Abbot)

Funny. I thought that I just said that Attribute::Property is an unacceptable solution to me. That means that it doesn't take away the issue.
I'm not disagreeing about that. You said that I indicated something; I cannot recall having indicated that exact thing, and tried to correct.
Let's not make a big deal out of everything. Feel offended if you wish, but please only do so knowing that I didn't mean "flawed" as an absolute condemnation and that no offense was intended. I like Perl for its tolerance towards almost all programming styles, but that doesn't mean I steer clear of discussion.
With OO I'd expect to be able to do something like create a Length module, Length objects can be accessed/set in various units (inches, meters, feet, miles, etc). An external user should have no idea what the internal representation is. How do I do it with lvalues?
In that rather specific case I would not use lvalues, or any setter method, for that matter. I'd be inclined to think of these values as immutable objects, and have something like:
But instead of using Length objects, I am much more likely to dictate that every length must be stored in meters, as a number. Possibly with the addition of utility functions to aid in conversion.
And whichever I do, I'll feel free to dislike people who categorically declare that my considered set of choices are flawed.
I'm sorry you make this about people. I wonder, though, how you survive PM if you take offense every time someone disagrees with you on a technical subject. You are of course free to dislike me, or any person. Even though we will probably never meet in person, I regret that you dislike *me* instead of only what I said.
