See also #SCARY.
S
SCARY
No-one can remember what the acronym stands for, not without googling, and even then it doesn't tell you much. Making a class or function template SCARY means to separate all that depends on the template arguments from all that doesn't depend on (some) template arguments, ensuring that identical code doesn't get recompiled over and over again for every instantiation of the template.
Cf. https://quuxplusone.github.io/blog/2019/08/02/the-tough-guide-to-cpp-acronyms/#scary-iterators
Originally merely coined for nested types like std::vector<T, A>::iterator (which never depends on A), it has come into use for other in-kind transformations, too, often being a special case of Extract Method or Extract Baseclass.
See also #DRY.
