This is not wonderful, but for me it's acceptable. Having that syntax support only for user defined types is quite better than having to use a syntax like stride(...) suggested by someone else.

For a simple but nice usage example of strides in Chapel language see pages 14-33 here:
http://chapel.cray.com/tutorials/SC10/M10-8-Samples.pdf

Strided grid description
var cell_centers     = [1..7 by 2, 1..5 by 2];
var vertical_edges   = [0..8 by 2, 1..5 by 2];
var horizontal_edges = [1..7 by 2, 0..6 by 2];
var vertices         = [0..8 by 2, 0..6 by 2];

(See the slides for more info.)
