It seems to replace the line
result = foo(a, b[0]);
with
result = foo("test", ""[0]);
and then complain that the constant expression ""[0] is wrong.  It's 
about distinguishing between static and dynamic arrays which I don't 
know how to do.

In your case, adding static if(b.sizeof) should do the trick: only empty 
static arrays have zero size.
