Multiparadigm languages. As discussed in Reference [MMN3] other programming 

perspectives like procedural, functional [Wik87] and constraint programming [FB92] 

have advantages for certain kinds of applications. It should be possible to combine all 

these perspectives into a unified perspective. The resulting language should not force a 

choice of one of the perspectives, but they should be integrated in a consistent way. 

BETA supports procedural programming and to some extent also functional 

programming. The Leda language  [Bud95] is a new proposal for a language supporting 

a number of perspectives.
