Multiparadigm Extensions to Java

In 1995 my students and I developed Leda, a multiparadigm language based on
the Pascal model.  Leda allowed programmers to create abstractions in an
object-oriented, functional, or logic programming style.  More recently, we
have been interested in recreating this work but this time using Java as the
language basis.  The objective is to add as few new operations as possible
and to make these operations seem as close to Java as possible so that they
seem to fit naturally in to the language.  To date we have proposed
facilities for breaking apart composed objects - sometimes called unboxing -
functions as first class values, for pass-by-name parameters, and for
relational (or logic) programming.
