What is "dylan"

Dylan may refer to:

Dylan is a multi-paradigm programming language that includes support for functional and object-oriented programming, and is dynamic and reflective while providing a programming model designed to support efficient machine code generation, including fine-grained control over dynamic and static behaviors. It was created in the early 1990s by a group led by Apple Computer.

A concise and thorough overview of the language may be found in the Dylan Reference Manual.

Dylan derives from Scheme and Common Lisp and adds an integrated object system derived from the Common Lisp Object System (CLOS). In Dylan, all values (including numbers, characters, functions, and classes) are first-class objects. Dylan supports multiple inheritance, polymorphism, multiple dispatch, keyword arguments, object introspection, pattern-based syntax extension macros, and many other advanced features. Programs can express fine-grained control over dynamism, admitting programs that occupy a continuum between dynamic and static programming and supporting evolutionary development (allowing for rapid prototyping followed by incremental refinement and optimization).

Dylan's main design goal is to be a dynamic language well-suited for developing commercial software. Dylan attempts to address potential performance issues by introducing "natural" limits to the full flexibility of Lisp systems, allowing the compiler to clearly understand compilable units (i.e., libraries).

Although deriving much of its semantics from Scheme and other Lisps—some implementations were in fact initially built within existing Lisp systems—Dylan has an ALGOL-like syntax rather than a Lisp-like prefix syntax.

Dylan is the thirteenth studio album by American singer-songwriter Bob Dylan, released on November 19, 1973 by Columbia Records. Compiled and issued by the label with no input from Dylan himself, it contains no original Dylan songs, the material consisting of two outtakes from Self Portrait and another seven from New Morning. It followed the artist's departure from Columbia for Asylum Records, and the announcement of his first major tour since 1966.

Although Dylan received very poor reviews, it managed to hit #17 in the US and become a gold record. It is the only Columbia Dylan album not to be reissued on compact disc in the North American market at the request of Dylan himself. Recently the album has been re-issued on digital disc included in the The Complete Album Collection Vol. One box set (2013). It became his first album never to chart in the UK, where his albums generally charted higher than in the US. In Europe, it was called Dylan – A Fool Such as I. A different recording of " Spanish Is the Loving Tongue" had been issued as the B-side of Dylan's 1971 single " Watching the River Flow". Until December 2009, the album was available on iTunes as part of the download Bob Dylan: The Collection. The first seven tracks were recorded in June 1970 for New Morning sessions; the last two recorded in April 1969 for Self Portrait sessions.

Dylan is a greatest hits collection by American singer-songwriter Bob Dylan. The collection was released on October 2, 2007 by Columbia Records and Legacy Recordings with worldwide distribution through Sony BMG. It was released as a single-disc CD and a three-disc Deluxe Edition (containing 51 songs), which was released as a digipack and a box set presented in replica-vinyl packaging, along with 10 postcards and an extensive booklet. The Deluxe Edition includes the 1971 version of " You Ain't Goin' Nowhere" although the album's liner notes erroneously state that it is the 1967 version.

Dylan is a Welsh male given name. It is derived from the word llanw, meaning "tide" or "flow" and the intensifying prefix dy-. Dylan ail Don was a character in Welsh mythology, but the popularity of Dylan as a given name in modern times arises from its use by poet Dylan Thomas. Its use as a surname stems from the adoption of the name by Bob Dylan. In Wales it was the most popular Welsh name given to babies in 2010.
