Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). [2] [3] Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. [4] Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific ...
Codon is a language with an ahead-of-time (AOT) compiler, that (AOT) compiles a statically-typed Python-like language with "syntax and semantics are nearly identical to Python's, there are some notable differences" [149] e.g. it uses 64-bit machine integers, for speed, not arbitrary like Python, and it claims speedups over CPython are usually ...
Programming languages and computing platforms that typically support reflective programming (reflection) include dynamically typed languages such as Smalltalk, Perl, PHP, Python, VBScript, and JavaScript. Also the .NET languages are supported and the Maude system of rewriting logic.
In computing, copy-and-patch compilation is a simple compiler technique intended for just-in-time compilation (JIT compilation) that uses pattern matching to match pre-generated templates to parts of an abstract syntax tree (AST) or bytecode stream, and emit corresponding pre-written machine code fragments that are then patched to insert memory addresses, register addresses, constants and ...

Logic-based languages specify a set of attributes that a solution must-have, rather than a set of steps to obtain a solution. Notable languages following this programming paradigm include: ALF; Alma-0; Curry; Datalog; Fril; Flix (a functional programming language with first-class Datalog constraints) Janus
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
A block is a grouping of code that is treated collectively. Many block syntaxes can consist of any number of items (statements, expressions or other units of code) – including one or zero. Languages delimit a block in a variety of ways – some via marking text and others by relative formatting such as levels of indentation.
