also GDC, and (i suspect) newer DMD releases have this problem

I think (I did not try all possibilities, but most) that this extends to any
non type arguments.

There was a related-sounding bug fixed in the last 1.x release.  Have 
you tried it there (1.033 I think)?

The code actually worked for a long time, but was broken again in 2.046.
Possibly caused by the bugfix for bug 945.
