It should be attainable to call a purpose meaningfully, to specify the requirements of its argument, and Obviously state the connection between the arguments and the result. An implementation is just not a specification. Check out to consider what a purpose does in addition to about how it does it.
Also, most true-environment initiatives involves code from quite a few sources, so standardizing on a single type for all code is the original source usually unachievable.
How granular really should namespaces be? All classes/capabilities meant to operate alongside one another and released together (as described in Sutter/Alexandrescu) or a little something narrower or broader?
