Thomas Fjellstrom said: A role is some behavior you want, some action you want to do. Basically you can compose your object out of distinct singular roles. So... multiple inheritance? Even syntax is the same... axilmar said: Yes, and the implementation of those methods could call the relevant <algorithm> functions. What if you wanted to make a new <algorithm>-like function yourself? How would you use your function on the built-in containers? I fail to see how your approach is more extensible than even the broken iterators of C++. "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

I fail to see how your approach is more extensible than even the broken iterators of C++. It depends. If I was using the new algorithm for an application, then I would do a stand-alone function. If I was making a library that extends the stl, I would do a standalone function and then subclasses of stl containers with methods that call the new standalone function. |

But what exactly would be the benefit of doing: class mycontainer does sortable does findable does foreachable does copyable does ... 200 more roles?
May-be an example? What would sortable look like, and what would it mean to the single linked list container I'd implement? |

The only thing the 'does' syntax reminds me of is 'Debby does...' ;-) |
