I think this should not be done. Note that even though code which is
D could reintroduce commas safely, C code will still exist at that

either do the same thing, or not compile, would be violated.
What would be an example of C code that would compile in a D
where the comma operator was used for tuples? Also why is cut and
pasting C code to D so important? If it's non-trivial surely
people will just use extern C. If it's trivial they can make the
minor improvements necessary.
This is valid in both C and C++:
i, j = 0, 1;
It is equivalent to the following:
i;
j = 0;
1;
Under the proposal, the "0, 1" would be void, so it wouldn't compile in
D. Therefore, the rule about moving C code to D safely is not violated.
