Are there any cases where you're using comma outside of for loops?
I wonder how much would break if were made illegal everywhere else.
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.
'most people'?
Occasionally, it's
useful to use one in an expression, but on the whole, it's just confusing and
error-prone.
It is confusing to people who don't know the language. It is a simple
construct. In my experience, it is certainly not error prone. If you are
aware that such an operator exists.
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.
Sure.
The resulting code may not be as compact, but it
wouldn't be hard to write.
It would be a PITA in some cases.
And unless you're dealing with a programmer who
uses it uncommonly often, not much code is going to break.
I _am_ such a programmer.
