UML Triple Distilled

A few months back I had given some training in (the) UML for my colleagues. The course was named UML Triple Distilled (a la vodka and Martin Fowler's classic UML Distilled).

The objective of the session was to present the UML from a non object-oriented perspective, as a communication and diagramming tool. People won't often say this, but, really, you don't necessarily have to be an OO guru to benefit from the UML.

In the coming days, I will be putting up slides from the session over here along with some reflections on the slides. Here's the introductory slide.

Function templates participate in name resolution for overloaded functions, but the rules are different. For a template to be considered in overload resolution, the type has to match exactly. If the types do not match exactly, the conversions are not considered and the template is simply dropped from the set of viable functions. That's what is known as "SFINAE" — Substitution Failure Is Not An Error.
