I'm sure that it would break code, but most people consider it bad practice to 
use the comma operator for much outside of for loops. Occasionally, it's 
useful to use one in an expression, but on the whole, it's just confusing and 
error-prone. And while it might break code to make the comma operator illegal 
outside of for loops, I would expect that fixing the broken code would 
generally be rather trivial. The resulting code may not be as compact, but it 
wouldn't be hard to write. And unless you're dealing with a programmer who 
uses it uncommonly often, not much code is going to break.
