Some of these weirdnesses will go away in Perl 6. It is still true that = will take its context from the left side, while += will enforce scalar context on both sides. What will change, however, is that any list-producing operator that returns its last value in scalar context in Perl 5 will instead produce a list reference in Perl 6.

That means there's no C-style comma operator in Perl 6. If you want the last value of a list, subscript it with [-1]. This also means that a slice in scalar context will not return the last value as it does in Perl 5. If you try that in Perl 6, you'll get a list reference, which will fail when you try to apply a scalar operator like += to it. (Perl 6 has a way to apply scalar operators to lists, but you have to be explicit.)
