[Schedule] Nonhierarchical OOP
programming best, chances are many of them will use the word
"inheritance" in their answer. I'd bet money that some of those
programmers will then go back to working on a project that makes good
use of duck typing, or of mixins. Such techniques are examples of
nonhierarchical OOP: object-oriented programming that eschews inheritance.
The current trend for new programming languages seems to be to include
more and more nonhierarchical OOP features. Some examples are new-style
interfaces in Google's Go, traits in Scala and Fortress, and roles in
Perl 6. This talk will focus on roles as provided by Perl 5's Moose
object system, as that seems to have the most uptake and is most
relevant for OSDC.tw's audience. Furthermore, because of roles' "class
building-block" nature, they are perhaps the best fit for open source of
any nonhierarchical system thus far.
Thankfully, nonhierarchical OOP is becoming mainstream. Because
seriously, multiple inheritance needs to die!
