At least I can imagine two reasonable cases.

1. If the code is ported from C/C++, breaking it is not reasonable.

2. If the two expressions are strongly related, using comma operator is
reasonable to represent the intensity. I think rather it's an *ability* to
represent code meaning by using code style.
