Yeah, this seems like an unnecessary limitation for exact matching. In 
other words, if your destination array exactly matches one or more of 
the arguments, it should be fine. Where the overlapping starts causing 
problems is something like this:

x[1..$] *= x[0..$-1];

I would love to see this limitation fixed.
