Partial application
In computer science, partial application (or partial function application) refers to the process of fixing a number of arguments to a function, producing another function of smaller arity. Given a function , we might fix (or 'bind') the first argument, producing a function of type . Evaluation of this function might be represented as . Note that the result of partial function application in this case is a function that takes two arguments. Partial application is sometimes incorrectly called currying, which is a related, but distinct concept.
String interpolation
In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values. It is a form of simple template processing or, in formal terms, a form of quasi-quotation (or logic substitution interpretation). The placeholder may be a variable name, or in some languages an arbitrary expression, in either case evaluated in the current context.
Métaclasse
En programmation, une métaclasse est une classe dont les instances sont des classes. Autrement dit, une métaclasse est la classe d'une classe. En programmation orientée objet, une classe est une sorte de module qui permet de créer un sous-ensemble d'objets. La classe décrit comment se comportent ses objets, fournit leur interface et compose la structure de leur état. La classe permet de créer de nouveaux objets au moyen d'un mécanisme appelé instanciation.
