Well, I'm not ready to file a bug report yet, but if you're desperate, I 
*think* this may do the trick for you (assuming you use 2.048):

in std/concurrency.d, line 382:

Change
if ( i < T.length )
to
static if ( i < T.length-1 )

This works (for me, at least), even without recompilation of phobos.
Mind you, I propose a hack made by hand, and Sean Kelly or other pros 
here may well find that I'm wrong, so it's at your own risk :)
