I think you got overly complicated answers.
I guess I'm confused as to why the D code isn't acting similar to the
Python code in the sense that you would expect "this" to reference the
"speed" property of the current instance and not statically reference
the parent. Am I having these issues because these attributes are being
initialized statically?
No, it's not because they're statically initialized. It's because fields
are not polymorphic.
Would using constructors be the way to go about this? I suppose I'm just
trying to find a way to implement fairly clean and intuitive object
oriented inheritance that isn't crippled by getters/setters, is resolved
at compile time, and doesn't impose any kind of runtime cost other than
what you would assume is associated with fundamental level OOP.
Either you can set the value in the constructor or turn "speed" in to a
method/property. I think it's easiest to set it in the constructor:
class Airplane : Vehicle
{
this()
{
speed = 100;
}
}
