%%jargon -- describing c++ templates

The official terminology describing class templates is clumsy and inconsistent with java/c#. Here's my own jargon. Most of the words (specialize, instantiate) already have a technical meaning, so I have to pick new words like "concretize" or "generic"

Rule #1) The last Word is key. Based on [[C++FAQ]]
- a class-template -- is a template not a class.
- a concretized template-class -- is a class not a template
--------------------------

"concretizing" a template... Officially terminology is "instantiating"

A "concretized class" = a "template class". Don't' confuse it with -- "concrete" class means non-abstract

A "unconcretized / generic class template" = a "class template".
(Note I won't say "unconcretized class"as it's self-contradictory.)

A "non-template" class is a regular class without any template.

Note concretizing = instantiating, completely different from specializing!

"dummy type name" is the T in the generic vector<T>

"type-argument", NOT "parameter", refers to an actual, concrete type like the int in vector<int>
