<ConsistencyModule:> element_g(?Index, ++List, ?Value)

   Value is the Index'th element of the integer list List, with native Gecode indexing.

Arguments
   ?Index              A (domain) variable or an integer.
   +Collection         A non-empty collection of integers or (domain) variable.
   ?Value              A (domain) variable or an integer (array notation accepted).

Type
   library(gfd)

Description
  This version of element/3 uses the native Gecode indexing, which starts 
  from 0, i.e. the first element of Collection has index 0. This is different 
  from normal ECLiPSe's indexing, which starts from 1.

  This predicate maps directly to Gecode's native implementation of the
  constraint, and may therefore be more efficient, but could also be
  incompatible with existing ECLiPSe code. 

   This constraint can be embedded in a constraint expression in its
   functional form (without the last argument).

  See element/3 for a more detailed description of this predicate.

Fail Conditions
   Fails if Value is not the Index'th element of Collection.
