Practices - Design Patterns

If using a widely used design pattern ( such as a visitor, provider, facade etc ) affix the name of the implementing class with the name of the pattern.

class rolling_stock_visitor;
class stock_price_change_observer;
class ogre_window_management_wrapper;

Rationale: Such names are descriptive of what the class really is, thus help to document to code.

When using a pattern use it only in the canonical form. Do not use the pattern infrastructure outside the pattern mechanisms.
