Pike

Pike is an interpreted, general-purpose, high-level, cross-platform, dynamic programming language, with a syntax similar to that of C.
Unlike many other dynamic languages, Pike is both statically and dynamically typed, and requires explicit type definitions.
It features a flexible type system that allows the rapid development and flexible code of dynamically typed languages, while still providing some of the benefits of a statically typed language.
Pike features garbage collection, advanced data types, and first-class anonymous functions, with support for many programming paradigms, including object-oriented, functional and imperative programming.
Pike is free software, released under the GPL, LGPL and MPL licenses.
