Python; Perl, via the metaclass pragma, as well as Moose; Ruby; Smalltalk; C++ (proposed for a possible inclusion in future version of the standard) [11] Some less widespread languages that support metaclasses include OpenJava, OpenC++, OpenAda, CorbaScript, ObjVLisp, Object-Z, MODEL-K, XOTcl, and MELDC. Several of these languages date from the ...
In some languages, such as Python, Ruby or Smalltalk, a class is also an object; thus each class is an instance of a unique metaclass that is built into the language. [4] [35] [36] The Common Lisp Object System (CLOS) provides metaobject protocols (MOPs) to implement those classes and metaclasses. [37]

The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
Apache Axis2 supports SOAP 1.1 and SOAP 1.2, and it has integrated support for the REST [2]: §14-9, [638] style of Web services. The same business-logic implementation can offer both a WS-* style interface as well as a REST/POX style interface simultaneously. Axis2/Java has support for Spring Framework. [2]: §14-9, [638]
