Guile kan bruges som sprog til udvikling af udvidelser til applikationer, definition af konfiguration eller udvikling af komponenter til at forbinde forskellige primtiver leveret af applikationen. Guile er det officielle sprog til udvikling af udvidelser til GNU-operativsystemet. <\/p>\n<p>Kernen i Guile er en effektiv virtuel maskine, der udf\u00f8rer et b\u00e6rbart instruktion s\u00e6t genereret af en s\u00e6rligt optimerende compiler.

Biblioteket, der f\u00f8lger med pakken, indeholder modul\u00e6re funktioner, der implementerer standard servicefunktioner som HTTP-protokol, XML-parsing og brug af objektorienterede programmeringsmetoder.<\/p>\n<p>Et n\u00f8gleinnovation i GNU Guile 3.0 er introduktionen af en JIT-compiler, ud over de tidligere tilbudte tolk og compiler til bytecode, der k\u00f8res i en s\u00e6rlig virtuel maskine bundet til applikationen i form af et biblioteks. JIT muligg\u00f8r generering af maskinkode i realtid og \u00f8ger betydeligt hastigheden af Guile-applikationer (test viser hastighedsfor\u00f8gelse p\u00e5 op til 4 gange).
