Comment 1 Walter Bright 2009-03-14 20:57:15 UTC 
I think this means std.variant in Phobos.
Comment 2 Neia Neutuladh 2009-03-14 21:16:47 UTC 
It might be worthwhile to examine the following:
http://dsource.org/projects/dmocks/browser/dunit/trunk/dunit/assertions/variant.d
http://dsource.org/projects/dmocks/browser/dunit/trunk/dunit/assertions/variant_array.d

The former defines yet another Variant; the latter defines a VariantArray that allows iteration as if it were an array of Variants.

This only applies to dynamic and static arrays; it doesn't apply to associative arrays.

They also reference my runtime traits module, linked for completeness:

Comment 3 Andrei Alexandrescu 2009-08-27 14:27:32 UTC 
I implemented a rather limited opApply for now, but I'll keep this open while I think of a better solution.
