Metaprogramming can be used to weave behavioral changes in a program, as done in aspect-oriented programming. For instance, metaprogramming can be used to inject feature flags or to explore possible patches for fixing bugs. Challenges. Some argue that there is a sharp learning curve to make complete use of metaprogramming features.

Some use cases for this pattern are static polymorphism and other metaprogramming techniques such as those described by Andrei Alexandrescu in Modern C++ Design. It also figures prominently in the C++ implementation of the Data, Context, and Interaction paradigm. In addition, CRTP is used by the C++ standard library to implement the …

Apache Groovy is a Java-syntax-compatible object-oriented programming language for the Java platform.It is both a static and dynamic language with features similar to those of Python, Ruby, and Smalltalk.It can be used as both a programming language and a scripting language for the Java Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates …

C++11 is a version of the ISO/IEC 14882 standard for the C++ programming language. C++11 replaced the prior version of the C++ standard, called C++03, and was later replaced by C++14.The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named C++0x because it was expected to be published …

D, also known as dlang, is a multi-paradigm system programming language created by Walter Bright at Digital Mars and released in 2001. Andrei Alexandrescu joined the design and development effort in 2007. Though it originated as a re-engineering of C++, D is a profoundly different language —features of D can be considered streamlined and expanded-upon ideas …

The eight-circuit model of consciousness is a hypothesis by Timothy Leary, later expanded on by Robert Anton Wilson and Antero Alli, that suggests "eight periods [circuits] and twenty-four stages of neurological evolution". The eight circuits, or eight systems or "brains", as referred by other authors, operate within the human nervous system.Each corresponds to its own imprint …

He co-founded and led Intentional Software (acquired by Microsoft in 2017), with the aim of developing and marketing ...

Both expressions have the same meaning and behave in exactly the same way. The latter form was introduced to avoid confusion, since a type parameter need not be a class until C++20. (It can be a basic type such as int or double.). For example, the C++ Standard Library contains the function template max(x, y) which returns the larger of x and y.That function template could be …

In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software,: 7 following the reusability principles.. Code reuse may be achieved by different ways depending on a complexity of a programming language chosen and range from a lower-level approaches like …

Dynamic type checking is the process of verifying the type safety of a program at runtime. Implementations of dynamically type-checked languages generally associate each runtime object with a type tag (i.e., a reference to a type) containing its type information. This runtime type information (RTTI) can also be used to implement dynamic dispatch, late binding, downcasting, …
