Are we sure this isn't expected?  I mean a null could mean a null string[], not
a null string.

string[] ret;
string[] a = null;

ret ~= a;
ret ~= a;

neither of these lines should do anything to ret, since they are empty arrays
of the same type.

I almost think the code in question should fail to compile for being too
ambiguous.
