Welcome to the ELENA wiki!
ELENA is a general-purpose language with late binding. It is multi-paradigm, combining features of functional and object-oriented programming. It supports both strong and weak types, run-time conversions, boxing and unboxing primitive types, direct usage of external libraries. Rich set of tools are provided to deal with message dispatching : multi-methods, message qualifying, generic message handlers. Multiple-inheritance can be simulated using mixins and type interfaces. Built-in script engine allows to incorporate custom defined scripts into your applications. Both stand-alone applications and Virtual machine clients are supported.
