Groovy

Groovy(http://groovy.codehaus.org/) is a dynamic language implemented on
the Java VM with strong Java integration. As Groovy's roots and
aims partially overlap with D's, some solutions might be interesting.

DISCLAIMER: I'm not a Groovy expert.

1) ranges

Groovy:
#
# assert (x in 2 .. 5);
#
# switch(y) {
#    case 1: break;
#    case 1900 .. 2006: break;
# }
#

current D:
#
# assert((2 <= x) && (x <= 5));
#
# switch(y) {
#    case 1: break;
#    default:
#       if((1900 <= y) && (y <= 2006)){
#          break;
#       }
# }

Especially the ranges support for switch/case is very useful.


2) literals for associative arrays

Groovy:
#
# def map = ['a': 1, 'b': 2, 'c': 3]
#

current D:
#
# int[char] map;
# map['a'] = 1;
# map['b'] = 2;
# map['c'] = 3;
#

Other useful features of Groovy depend too much on the VM
(e.g. dynamic extending of classes) for integration into D.
