Thanks Steve (and Chad).  Summary: underspecified, varying

Steve, what's the best way for me to report this?  Are spec 
issues lumped in with the other bugzilla reports?

Yep. You can file under dlang.org with the spec keyword.

Although this looks like it's not exactly a spec issue. I'd 
start it as a dmd bug (I don't know the exact interaction with 
the compiler and the library). It might also be a druntime bug.

FWIW   ..using gdc Debian 8.3.0-6,   dst[]= generates a range 
error
    auto a = [1, 2, 3];
    auto b = [4, 5, 6];
    int[] dst = new int[4]; // note the extra element
    dst[] = a[] + b[];
    writeln(dst[3]);
