You guys!!! Everyone knows that all of these issues were sorted out in the Algol68 report, where semi-colons were chosen as indicating activities that must take place in sequential fashion, and commas were chosen as indicating activities that could happen in a random order.
So A := 38; B := A was guaranteed to evaluate correctly, whereas A := 38, B := A might not since it could be that the value to which A refrers at the time of the second assignment statement is undefined. A lot of these ideas made their way into C eventually, including the idea that the order of evaluation of expressions in a comma-delineated list was undefined.
