Common acronyms

[Philippe Sigaud]

Today I saw one thread with DSEL and another with SFINAE.
I was wondering, is everyone reading the forums here at ease with 
the acronyms bandied around?

We (I) could create a wiki page to help somewhat, if only to help 
newcomers not used to the C/C++-specific terms that are commonly 
used here. Many people here (if not a majority) are also 
non-native English speakers and I know that *I* had trouble with 
some words (NIH was new for me). Maybe people can just google it, 
but it seems friendlier to have a wiki page.

Yes? No? Could people here give me some ideas?

- RTTI : runtime-time type information 
(http://en.wikipedia.org/wiki/Run-time_type_information)  <your 
explanation here>

- SFINAE : Substitution Failure is not an Error 
(http://en.wikipedia.org/wiki/Substitution_failure_is_not_an_error) 
<your explanation here>

- RAII : Resource Acquisition is Initialization <your explanation 
here>

- NIH : Not Invented Here. Also: NIH Syndrome. When a community 
starts writing its own tools in its own language, (deliberately) 
ignoring there are more mature tools available elsewhere.

- DSL : Domain-Specific Language. A small sub-language dedicated 
to a particular domain or problem. Examples are regexes, string 
formatters (%d, %s, ...).

- DSEL : Domain-Specific Embedded Language. A DSL used inside a 
more general programming language. Also known as an internal DSL, 
as opposed to an external DSL.
